Convert the boardinfo declaration to C99 format to make it less error
prone and easier to maintain.

For aesthetics, move the declaration closer to the struct definition.

H Hartley Sweeten 8a6573a875 staging: comedi: adl_pci6208: use comedi_offset_munge()
Use comedi_offset_munge() to munge the offset binary values from the
comedi core into the two's complement form that the hardware expects.

This removes the hard coded assumption that the analog outputs are
16-bits and instead does the munging based on the s->maxdata.

H Hartley Sweeten f0b215d6e8 staging: comedi: core: introduce comedi_offset_munge()
The comedi core expects the data to/from analog subdevices to be
in offset binary coding. This means that a value of '0' represents
the most negative and a value of 's->maxdata' the most positive
signal of the analog subdevice.

Many comedi drivers require the data written to the analog outputs,
or returned from the analog inputs, be in two's complement format.

Introduce a helper function to munge the data for analog subdevices.
This function simply inverts the sign bit and masks the result by
's->maxdata' to keep the result in range for the subdevice. The
strange:

  return val ^ s->maxdata ^ (s->maxdata >> 1);

is equivalent to:

  return (val ^ ((s->maxdata + 1) >> 1) & s->maxdata;

as long as s->maxdata is a value of the form (1 << n) - 1. This
avoids the 32-bit unsigned overflow for a s->maxdata of 0xffffffff.

H Hartley Sweeten 20fb170b29 staging: comedi: adl_pci6208: save raw data for analog output readback
This driver munges the raw data from the comedi core into its two's
complement form before writing it to the hardware. The last value
written to the hardware is saved in the private data for readback.

Since the comedi core always expects the data to be in offset binary
coding, make sure to save the un-munged value for readback.

Also, prefetch the current readback value before attempting to update
the hardware. This ensures that the readback value is correct if no
values are actually written.

Greg Kroah-Hartman 3ffdea3fec First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle
A number of new drivers and some new functionality + a lot of cleanups
 all over IIO.
 
 New Core Elements
 
 1) New INT_TIME info_mask element for integration time, which may have
    different effects on measurement noise and similar, than an amplifier
    and hence is different from existing SCALE.  Already existed in some
    drivers as a custom attribute.
 
 2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
    case of filling the last 64 bits of data to be passed to the buffer with
    a timestamp.  Applied to lots of drivers. Cuts down on repeated code and
    moves a slightly fiddly bit of logic into a single location.
 
 3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
    of elements such as sampling_frequency which is typically shared by all
    input channels on a device.  This reduces code and makes these controls
    available from in kernel consumers of IIO devices.
 
 New drivers
 
 1) MCP3422/3/4 ADC
 
 2) TSL4531 ambient light sensor
 
 3) TCS3472/5 color light sensor
 
 4) GP2AP020A00F ambient light / proximity sensor
 
 5) LPS001WP support added to ST pressure sensor driver.
 
 New driver functionality
 
 1) ti_am335x_adc Add buffered sampling support.
    This device has a hardware fifo that is fed directly into an IIO kfifo
    buffer based on a watershed interrupt.  Note this will act as an example
    of how to handle this increasingly common type of device.
    The only previous example - sca3000 - take a less than optimal approach
    which is largely why it is still in staging.
    A couple of little cleanups for that new functionality followed later.
 
 Core cleanups:
 
 1) MAINTAINERS - Sachin actually brought my email address up to date because
    I said I'd do it and never got around to it :)
 
 2) Assign buffer list elements as single element lists to simplify the
    iio_buffer_is_active logic.
 
 3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake
    up threads waiting for poll notifications.
 
 4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface.
 
 5) Change iio_push_to_buffers to take a void * pointer so as to avoid some
    annoying and unnecessary type casts.
 
 6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long.
 
 7) Various minor tidy ups.
 
 Driver cleanups (in no particular order)
 
 1) Another set of devm_ allocations patches from Sachin Kamat.
 
 2) tsl2x7x - 0 to NULL cleanup.
 
 3) hmc5843 - fix missing > in MODULE_AUTHOR
 
 4) Set of strict_strto* to kstrto* conversions.
 
 5) mxs-lradc - fix ordering of resource removal to match creation
 
 6) mxs-lradc - add MODULE_ALIAS
 
 7) adc7606 - drop a work pending test duplicated in core functions.
 
 8) hmc5843 - devm_ allocation patch
 
 9) Series of redundant breaks removed.
 
 10) ad2s1200 - pr_err -> dev_err
 
 11) adjd_s311 - use INT_TIME
 
 12)  ST sensors - large set of cleanups from Lee Jones and removed restriction
     to using only triggers provided by the st_sensors themselves from
     Dennis Ciocca.
 
 13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.
 
 14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
     suspend / resume functions.
 
 15) max1363 - use defaults for buffer setup ops as provided by the triggered
     buffer helpers as they are the same as were specified in max1363 driver.
 
 16) Trivial tidy ups in a number of other drivers.

13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.

14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
    suspend / resume functions.

15) max1363 - use defaults for buffer setup ops as provided by the triggered
    buffer helpers as they are the same as were specified in max1363 driver.

16) Trivial tidy ups in a number of other drivers.

Greg Kroah-Hartman 6174081013 First round of IIO fixes for 3.12
A series of wrong 'struct dev' assumptions in suspend/resume callbacks
 following on from this issue being identified in a new driver review.
 One to watch out for in future.
 
 A number of driver specific fixes
 1) at91 - fix a overflow in clock rate computation
 2) dummy - Kconfig dependency issue
 3) isl29018 - uninitialized value
 4) hmc5843 - measurement conversion bug introduced by recent cleanup.
 5) ade7854-spi - wrong return value.
 
 Some IIO core fixes
 1) Wrong value picked up for event code creation for a modified channel
 2) A null dereference on failure to initialize a buffer after no buffer has
    been in use, when using the available_scan_masks approach.
 3) Sampling not stopped when a device is removed. Effects forced removal
    such as hot unplugging.
 4) Prevent device going away if a chrdev is still open in userspace.
 5) Prevent race on chardev opening and device being freed.
 6) Add a missing iio_buffer_init in the call back buffer.
 
 These last few are the first part of a set from Lars-Peter Clausen who
 has been taking a closer look at our removal paths and buffer handling
 than anyone has for quite some time.

Jun'ichi Nomura 75afb35299 block: Add nr_bios to block_rq_remap tracepoint
Adding the number of bios in a remapped request to 'block_rq_remap'
tracepoint.

Request remapper clones bios in a request to track the completion
status of each bio. So the number of bios can be useful information
for investigation.
