introduces spaces where needed.
Spaces before semicolons are prohibited by the official coding style

This was originally reported by Craig Markwardt on Zubair Lutfullah's
blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email
address known.
The code first counted the number of enabled channels, then created an
array to hold information about them. The code that filled this array then
stored whether a given element was enabled inside the array. Curriously
this element was never used. Craig's patch added a local temporary variable
to avoid the buffer overrun. Jonathan then removed the original enabled
element of the structure as it was not needed at all.

This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.
This conversion relies on a few sets of patches in branches from outside
the Tegra tree:
1) A patch to add an DMA channel request API which allows deferred probe
to be implemented.
2) A patch to implement a common part of the of_xlate function for DMA
controllers.
3) Some ASoC patches (which in turn rely on (1) above), which support
deferred probe during DMA channel allocation.
4) The Tegra clock driver changes for 3.14.
Consequently, this branch is based on a merge of all of those external
branches.
In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:
a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
conflicts.
b) The DRM tree, which introduces new code that relies on the reset
controller framework introduced in this branch, and to avoid
conflicts.

New drivers
* HID inclinometer driver.
* DHT11 humidity driver. Note that previous humidity drivers have been in
hwmon, but no one was ever entirely happy with that, and they should find
a more comfortable home in IIO (their original placement in hwmon was my
fault - oops). As this is our first humidity driver, core support is also
added.
New features
* Two of mxs-lradc channels are internally wired to a temperature sensor,
make this explicit in the driver by providing the relevant temperature
channel.
* Add support for blocking IO on buffers.
* Add a data_available call back to the interface between buffer implementations
and the core. This is much cleaner than the old, 'stufftoread' flag.
Implemented in the kfifo buffer.
Cleanups
* Last user of the old event configuration interface is converted and the
old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard
work!
* Replace all remaining instances of the IIO_ST macro with explicit filling
of the scan_type structure within struct iio_chan_spec. This macro was a
bad idea, that rapidly ceased to cover all elements of the structure.
Miss reading of the macro arguements has led to a number of bugs so lets
just get rid of it. The final removal patch is awaiting for some fixes
to make their way into mainline.
In a couple of drivers, no elements of scan_type were even being used so
in those case, it has been dropped entirely.
* Drop a couple of of_match_ptr helper uses in drivers where devicetree is
not optional and hence the structures being protected by this always exist.
* Fix up some cases where data was read from a device in a particular
byte order, but he code placed it into a s16 or similar. These were
highlighted by Sparse.
* Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers
core code.
* ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code
and possibly avoiding issues with i2c bus drivers that assume they can dma
directly into the buffer. Note that this cannot currently happen as the the
i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually
passed to the bus driver. I missed this element of the commit message
and don't think it is major enough to rebase the iio tree.
* ad5791 and ad5504 stop storing buffers on the stack for an SPI driver.
Unlike the i2c drivers, this is a real issue for SPI drivers which can dma
directly into the buffer supplied.

The 'counter_index' parameter to all the functions is the ni_gpct_device

The omap24xx driver and the tcm825x sensor driver are the only two
remaining drivers to still use the old deprecated v4l2-int-device API.
Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device
API is used by out-of-tree drivers (MXC platform). This is a very bad situation
since as long as this deprecated API stays in the kernel there is no reason for
those out-of-tree drivers to convert.
This patch moves v4l2-int-device and the two drivers that depend on it to
staging in preparation for their removal.
If someone would be interested in getting these drivers to work, then start with
this since it's not very far from the state where they used to work:

During the last media summit meeting it was decided to move this driver to
staging as the first step to removing it altogether.
Most webcams covered by this driver are now supported by gspca. Nobody has the
hardware to convert the remaining devices to gspca.
This driver needs a major overhaul to have it conform to the latest frameworks
and compliancy tests.
Without hardware, however, this is next to impossible. Given the fact that
this driver seems to be pretty much unused (it has been removed from Fedora
several versions ago and nobody complained about that), we decided to drop
this driver.
This patch moves it to staging. Some time in 2014 we will drop it completely.

Two small things were left out. The compat_ioctl ptr assignment,

arches.
This patch resolves this issue by adding a padding entry after

RT_MUTEXES can be configured out of the kernel, causing compile
problems with ION.
To quote Colin:
"rt_mutexes were added with the deferred freeing feature. Heaps need
to return zeroed memory to userspace, but zeroing the memory on every
allocation was causing performance issues. We added a SCHED_IDLE
thread to zero memory in the background after freeing, but locking the
heap from the SCHED_IDLE thread might block a high priority allocation
thread for a long time.
The lock is only used to protect the heap's free_list and
free_list_size members, and is not held for any long or sleeping
operations. Converting to a spinlock should prevent priority
inversion without using the rt_mutex. I'd also rename it to free_lock
to so it doesn't get used as a general heap lock."
Thus this patch converts the rt_mutex usage to a spinlock and
renames the lock free_lock to be more clear as to its use.
I also had to change a bit of logic in ion_heap_freelist_drain()
to safely avoid list corruption.

However, DRM already serialises mode sets with a mutex, which prevents

On x86 it is possible to have a 32-bit userspace and a 64-bit kernel.

When a dynamically created comedi device is being automatically removed
by a call to `comedi_auto_unconfig()` from the lower level driver,
`comedi_device_cleanup()` is called to perform the detachment from the
lower level driver. If the comedi device is open at the time,
`dev->use_count` will be the the number of outstanding opens. The
function currently decrements the the module counts of the "comedi"
module and the low-level driver module by this amount and reduces
`dev->use_count` to zero. There are various problems with this as the
`release` file operation handler `comedi_close()` also decrements
`dev->use_count` and decrements the module usage counts. This means
that `dev->use_count` and the module counts can end up negative.
Also, the assumed one-to-one relationship between the file open count
and the low-level module usage count is invalid and can get screwed up.
We only want to stop the low-level module being unloaded while a comedi
device using the module has an open file object.
Also, there is no need to manipulate the module count of the core
"comedi" module at all since the comedi module is the owner of the file
operations structure and the system will not unload the module while
there are open file objects using it.
Correct the bugs and simplify as follows:
1. Get rid of the module count manipulations of the core "comedi" module
(`THIS_MODULE`) altogether.
2. Don't alter `dev->use_count` in `comedi_device_cleanup()` as it
should only be altered by the `open` and `release` file operation
handlers `comedi_open()` and `comedi_close()`.
3. Increment the low-level module count for the following reasons:
a) In `comedi_open()` if the open count was zero and the comedi device
is attached to the low-level driver.
b) When the `COMEDI_DEVCONFIG` ioctl is used to manually attach an
unattached comedi device to a low-level driver. The open count
will be greater than zero at this time. The actual increment of
the low-level module count is already done by
`comedi_device_attach()`.
4. Decrement the low-level module count for the following reasons:
a) In `comedi_close()` if the open count was 1 and the comedi device
is attached to the low-level driver.
b) In `comedi_device_cleanup()` (called via `comedi_auto_unconfig()`
--> `comedi_release_hardware_device()` -->
`comedi_free_board_dev()` when the comedi device is automatically
unconfigured due to action by the low-level driver) if the device
was attached (which it should be) and open count was non-zero
(greater than zero).
c) When the `COMEDI_DEVCONFIG` ioctl is used to manually detach the
comedi device from the low-level driver. The open count will be
greater than zero at this time.
The open count should never go negative. Parts 3 and 4 ensure that the
low-level module usage count is incremented on entering the state where
the comedi device is attached to the low-level driver AND the open count
is greater than zero, and is decremented on leaving that state.

When a dynamically allocated `struct comedi_device` gets automatically
unconfigured by a call to `comedi_auto_unconfig()` from a lower-level
driver's bus removal function (e.g. when a USB device is disconnected),
the class device in `dev->class_dev` (where `dev` points to the `struct
comedi_device`) is destroyed by a call to `device_destroy()` that
matches a previous call to `device_create()`.
However, if the `struct comedi_device` is still associated with an open
file object, the now invalid `dev->class_dev` pointer may still be
passed to `dev_printk()` (via `dev_dbg()` etc.), producing bogus output
or worse.
To fix this, call `get_device()` on the class device if
`device_create()` was successful. Add a matching call to `put_device()`
in `comedi_dev_kref_release()` when the `struct comedi_device` is freed.
The calls to `dev_dbg()` etc. after the call to `device_destroy()` will
still produce valid output, although the device will have been
unregistered in sysfs.

At some point, Measurement Computing / ComputerBoards redesigned the
PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip.
This meant they had to put their hardware registers in the PCI BAR 2
region instead of PCI BAR 1. Unfortunately, they kept the same PCI
device ID for the new design. This means the driver recognizes the
newer cards, but doesn't work (and is likely to screw up the local
configuration registers of the PLX chip) because it's using the wrong
region.
Since the PCI subvendor and subdevice IDs were both zero on the old
design, but are the same as the vendor and device on the new design, we
can tell the old design and new design apart easily enough. Split the
existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new
entries, referenced by different entries in the PCI device ID table

This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness. This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
converting the channel and generating thoroughly trashed data.

Commit 559c71fe5d ("Staging: TIDSPBRIDGE: Use vm_iomap_memory for
mmap-ing instead of remap_pfn_range") had the effect of inadvertently
shifting the start of the physical memory area mapped by
pdata->phys_mempool_base. Correct this by subtracting that shift before
calling vm_iomap_memory() and adding it back afterwards.
