      ALSA: hda - Use standard workqueue for unsol and jack events · 2f35c630
      由 Takashi Iwai 提交于 
      The events that are handled by HD-audio drivers are no frequent and
urgent ones, so we can use the standard workqueue without any problem
nowadays.

      ALSA: hda - Allocate hda_pcm objects dynamically · bbbc7e85
      由 Takashi Iwai 提交于 
      So far, the hda_codec object kept the hda_pcm list in an array, and
the codec driver was expected to assign the array.  However, this
makes the object life cycle management harder, because the assigned
array is freed at the codec driver detach while it might be still
accessed by the opened streams.

In this patch, we allocate each hda_pcm object dynamically and manage
it as a linked list.  Each object has a kref refcount, and both the
codec driver binder and the PCM open/close touches it, so that the
object won't be freed while in use.

      ALSA: hda - Add card field to hda_codec struct · 6efdd851
      由 Takashi Iwai 提交于 
      Allow the codec object to have an individual card pointer.  Not only
this simplifies the redirections in many places, also this will allow
us to make each codec assigned to a different card object.

      ALSA: hda - Bind codecs via standard bus · d8a766a1
      由 Takashi Iwai 提交于 
      Now we create the standard HD-audio bus (/sys/bus/hdaudio), and bind
the codec driver with the codec device over there.  This is the first
step of the whole transition so that the changes to each codec driver
are kept as minimal as possible.

Each codec driver needs to register hda_codec_driver struct containing
the currently existing preset via the new helper macro
module_hda_codec_driver().  The old hda_codec_preset_list is replaced
with this infrastructure.  The generic parsers (for HDMI and other)
are also included in the preset with the special IDs to bind
uniquely.

In HD-audio core side, the device binding code is split to
hda_bind.c.  It provides the snd_hda_bus_type implementation to match
the codec driver with the given codec vendor ID.  It also manages the
module auto-loading by itself like before: when the matching isn't
found, it tries to probe the corresponding codec modules, and finally
falls back to the generic drivers.  (The special ID mentioned above is
set at this stage.)

The only visible change to outside is that the hdaudio sysfs entry now
appears in /sys/bus/devices, not as a sound class device.

More works to move the suspend/resume and remove ops will be
(hopefully) done in later patches.

      ALSA: hda - Get rid of action field from struct hda_jack_tbl · 62f949bf
      由 Takashi Iwai 提交于 
      The action value assigned to each hda_jack_tbl entry is mostly
superfluous.  The actually used values are either the widget NID or a
value specific to the callback.

The former case can be simply replaced by a reference to widget NID
itself.  The only place doing the latter is STAC/IDT codec driver for
the powermap handling.  But, the code doesn't need to check the action
field at all -- the function jack_update_power() is called either with
a specific pin or with NULL.  So the check of jack->action can be
removed completely there, too.

      ALSA: hda/ca0132 - Don't try loading firmware at resume when already failed · e24aa0a4
      由 Takashi Iwai 提交于 
      CA0132 driver tries to reload the firmware at resume.  Usually this
works since the firmware loader core caches the firmware contents by
itself.  However, if the driver failed to load the firmwares
(e.g. missing files), reloading the firmware at resume goes through
the actual file loading code path, and triggers a kernel WARNING like:

 WARNING: CPU: 10 PID:11371 at drivers/base/firmware_class.c:1105 _request_firmware+0x9ab/0x9d0()

For avoiding this situation, this patch makes CA0132 skipping the f/w
loading at resume when it failed at probe time.

      ALSA: hda - Replace with standard printk · 4e76a883
      由 Takashi Iwai 提交于 
      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.
