ALSA: hda: Fix krealloc() with __GFP_ZERO usage

2016-08-20T16:09:24+00:00

commit 33baefe5e72f17a6df378e48196cd8cada11deec upstream.

krealloc() doesn't work always properly with __GFP_ZERO flag as
expected.  For clearing the reallocated area, we need to clear
explicitly instead.

ALSA: hda - Add / fix kernel doc comments

2015-10-28T11:37:29+00:00

Give some readable comment in kernel doc style for each exported
function, as I promised in the previous meetings.  While we're at it,
fix the wrong comments, too.

ALSA: hda - Advertise MODALIAS in uevent

2015-10-20T08:15:53+00:00

By setting the MODALIAS variable in uevents, userspace helpers will be
enabled to load modules via the module alias associated with a device.

This information is required to automatically load HDA codec drivers
instead of having to explicitly request the various modules in the HDA
core code.

[Note that currently the legacy HDA controller driver tries to bind
 codec modules manually.  It's for supporting the fallback generic
 drivers.  This new udev modalias support was added rather for ASoC
 HDA ext drivers, since this addition itself won't hurt the legacy HDA
 -- tiwai]

[Use the common helper function to generate the modalias -- tiwai]

ALSA: hda - Add a common helper to give the codec modalias string

2015-10-20T08:14:59+00:00

This patch provide a new common helper function,
snd_hdac_codec_modalias(), to give the codec modalias name string.
This function will be used by multiple places in the later patches.

ALSA: hda - Add hduadio support to DEVTABLE

2015-10-20T08:14:42+00:00

For generating modalias entries automatically, move the definition of
struct hda_device_id to linux/mod_devicetable.h and add the handling
of this record in file2alias helper.  The new modalias is represented
with combination of vendor id, device id, and api version as
"hdaudio:vNrNaN".

This patch itself doesn't convert the existing modaliases.  Since they
were added manually, this patch won't give any regression by itself at
this point.

[Modified the modalias format to adapt the api_version field, and drop
 invalid ANY_ID definition by tiwai]

ALSA: hda - consolidate chip rename functions

2015-10-15T12:05:28+00:00

A few multiple codec drivers do renaming the chip_name string but all
these are open-coded and some of them have even no error check.  Let's
make common helpers to do it properly.

Compiling the hdac extended core on arm fails with below error:

This is fixed by explicitly including io.h

The current codec helpers are local to hda code and needs to be moved to
core so that other users can use it.
The helpers to read/write the codec and to check the
power state of widgets is copied
