Takashi Iwai bc340c3350 ALSA: als300: Remove function debug prints

Takashi Iwai 4e76a8833f ALSA: hda - Replace with standard printk
Use dev_err() and co for messages from HD-audio controller and codec
drivers.  The codec drivers are mostly bound with codec objects, so
some helper macros, codec_err(), codec_info(), etc, are provided.
They merely wrap the corresponding dev_xxx().

There are a few places still calling snd_printk() and its variants
as they are called without the codec or device context.

Takashi Iwai b989d0444b ALSA: hda - Enable sysfs attributes without CONFIG_SND_HDA_RECONFIG
Some sysfs attributes like init_pin_configs or vendor_name are really
basic and should be available no matter whether the codec driver is
re-configurable or not.  Put them out of #ifdef
CONFIG_SND_HDA_RECONFIG and allow the read-only accesses.

Takashi Iwai 648a8d276e ALSA: hda - Add sysfs to codec object, too
We have currently sysfs attributes for each hwdep, but basically these
should belong to the codec itself, per se.  Let's add them to the
codec object while keeping them for hwdep as is for compatibility.

While we are at it, split the sysfs-related stuff into a separate
source file, hda_sysfs.c, and keep only the stuff necessary for hwdep
in hda_hwdep.c.

Takashi Iwai 13aeaf6801 ALSA: hda - Create own device struct for each codec
As the HD-audio is treated individually in each codec driver, it's
more convenient to assign an own struct device to each codec object.
Then we'll be able to use dev_err() more easily for each codec, for
example.

For achieving it, this patch just creates an object "hdaudioCxDy".
It belongs to sound class instead of creating a new bus, just for
simplicity, at this stage.  No pm ops is implemented in the device
struct level but currently it's merely a container.  The PCM and hwdep
devices are now children of this codec device.

Takashi Iwai 72620d6048 ALSA: Clean up snd_device_*() codes
A few code cleanups and optimizations.  In addition, drop
snd_device_disconnect() that isn't used at all, and drop the return
values from snd_device_free*().

Another slight difference by this change is that now the device state
will become always SNDRV_DEV_REGISTERED no matter whether dev_register
ops is present or not.  It's for better consistency.  There should be
no impact for the current tree, as the state isn't checked.

Takashi Iwai 289ca025ee ALSA: Use priority list for managing device list
Basically, the device type specifies the priority of the device to be
registered / freed, too.  However, the priority value isn't well
utilized but only it's checked as a group.  This results in
inconsistent register and free order (where each of them should be in
reversed direction).

This patch simplifies the device list management code by simply
inserting a list entry at creation time in an incremental order for
the priority value.  Since we can just follow the link for register,
disconnect and free calls, we don't have to specify the group; so the
whole enum definitions are also simplified as well.

The visible change to outside is that the priorities of some object
types are revisited.  For example, now the SNDRV_DEV_LOWLEVEL object
is registered before others (control, PCM, etc) and, in return,
released after others.  Similarly, SNDRV_DEV_CODEC is in a lower
priority than SNDRV_DEV_BUS for ensuring the dependency.

Also, the unused SNDRV_DEV_TOPLEVEL, SNDRV_DEV_LOWLEVEL_PRE and
SNDRV_DEV_LOWLEVEL_NORMAL are removed as a cleanup.

Avoid traversing the device object list of the card instance just for
checking the PCM streams.  The driver's private object already
contains the array of substream pointers, so it can be simply looked
through.  The card internal may be restructured in future, thus better
not to rely on it.

Also, this fixes the possible deadlocks in PCM mutex.  Instead of
taking multiple PCM mutexes, just take the common mutex in all
places.  Along with it, rename prepare_mutex as pcm_mutex.

Kevin Hao 06b29e76a7 of: search the best compatible match first in __of_match_node()
Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.

Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

 "The following trilogy of patches brings you:

   - fix for a long standing math overflow issue with HZ < 60

   - an onliner fix for a corner case in the dreaded tick broadcast
     mechanism affecting a certain range of AMD machines which are
     infested with the infamous automagic C1E power control misfeature

   - a fix for one of the ARM platforms which allows the kernel to
     proceed and boot instead of stupidly panicing for no good reason.
     The patch is slightly larger than necessary, but it's less ugly
     than the alternative 5 liner"

Linus Torvalds 9bd01b9bbd Two fixes in the tracing utility.
The first is a fix for the way the ring buffer stores timestamps.
 After a restructure of the code was done, the ring buffer timestamp
 logic missed the fact that the first event on a sub buffer is to have
 a zero delta, as the full timestamp is stored on the sub buffer itself.
 But because the delta was not cleared to zero, the timestamp for that
 event will be calculated as the real timestamp + the delta from the
 last timestamp. This can skew the timestamps of the events and
 have them say they happened when they didn't really happen. That's bad.
 
 The second fix is for modifying the function graph caller site.
 When the stop machine was removed from updating the function tracing
 code, it missed updating the function graph call site location.
 It is still modified as if it is being done via stop machine. But it's not.
 This can lead to a GPF and kernel crash if the function graph call site
 happens to lie between cache lines and one CPU is executing it while
 another CPU is doing the update. It would be a very hard condition to
 hit, but the result is sever enough to have it fixed ASAP.

Filipe David Borba Manana 93de4ba864 Btrfs: use right clone root offset for compressed extents
For non compressed extents, iterate_extent_inodes() gives us offsets
that take into account the data offset from the file extent items, while
for compressed extents it doesn't. Therefore we have to adjust them before
placing them in a send clone instruction. Not doing this adjustment leads to
the receiving end requesting for a wrong a file range to the clone ioctl,
which results in different file content from the one in the original send
root.

Wolfram Sang 79970db213 i2c: mv64xxx: refactor message start to ensure proper initialization
Because the offload mechanism can fall back to a standard transfer,
having two seperate initialization states is unfortunate. Let's just
have one state which does things consistently. This fixes a bug where
some preparation was missing when the fallback happened. And it makes
the code much easier to follow. To implement this, we put the check
if offload is possible at the top of the offload setup function.

pci_dev, we can reduce the inclusion of linux/pci.h, too.
