      ALSA: hda - Create own device struct for each codec · 13aeaf68
      由 Takashi Iwai 提交于 
      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.

      ALSA: hda - Manage each codec instance individually · 2565c899
      由 Takashi Iwai 提交于 
      Now each snd_hda_codec instance is managed via the device chain, the
registration and release are done by its callback instead of calling
from bus.

      ALSA: Clean up snd_device_*() codes · 72620d60
      由 Takashi Iwai 提交于 
      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.

      ALSA: Use priority list for managing device list · 289ca025
      由 Takashi Iwai 提交于 
      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.

      ALSA: hwdep: Allow to assign the given parent · 71e2e1c1
      由 Takashi Iwai 提交于 
      Just like PCM, allow hwdep to be assigned to a different parent device
than the card.  It'll be used for the HD-audio codec device in the
later patches.

      ALSA: hwdep: Take private_data as drvdata for sysfs · f806bdb2
      由 Takashi Iwai 提交于 
      For referring to a different object from sysfs ops, take hwdep
private_data as stored via dev_set_drvdata() at creating the device
object.  In that way, the same sysfs ops can be used by different
device types.

      ALSA: Create sysfs attribute files via groups · caa751ba
      由 Takashi Iwai 提交于 
      Instead of calling each time device_create_file(), create the groups
of sysfs attribute files at once in a normal way.  Add a new helper
function, snd_get_device(), to return the associated device object,
so that we can handle the sysfs addition locally.

Since the sysfs file addition is done differently now,
snd_add_device_sysfs_file() helper function is removed.

      ALSA: hda - Avoid codec D3 for keeping mute LED up on Lenovo Yxx0 · bf68665d
      由 Takashi Iwai 提交于 
      The GPIO line used for the mute LED control on Lenovo Yxx0 laptops is
cleared unexpectedly when the codec goes to D3, typically by
power-saving.  For avoiding it, add a power filter in the fixup.

      ALSA: hda - Add a fixup for HP Folio 13 mute LED · 37c367ec
      由 Takashi Iwai 提交于 
      HP Folio 13 may have a broken BIOS that doesn't set up the mute LED
GPIO properly, and the driver guesses it wrongly, too.  Add a new
fixup entry for setting the GPIO pin statically for this laptop.
