PCM Midlevel,ALSA Core,USB generic driver
- prepare callback can sleep if a flag is given in pcm->info_flags.
- usbaudio driver uses non-atomic prepare callback for synchronization
  of pending unlinked urbs.
- async_unlink option of usbaudio driver is enabled as default now.
- fixed the initialization of pseudo-dma pointers in usbaudio.

PCM Midlevel
- clear the status record before calling snd_pcm_status() in proc read.
  this will prevent to show bogus values when status = OPEN.

Digigram VX core
- added hw_constraint to align 4bytes.
  this will solve the 24bit problem on vx222.

USB generic driver
fix by Clemens Ladisch <clemens@ladisch.de>:

- don't clear active_mask bits until it's clear that the URB is _not_
  resubmitted, to prevent a race with unlinking
- initialize active_mask and unlink_mask each time before URBs are
  started
- don't call sleeping functions in trigger callback

USB generic driver
- clear unlink_mask bit in the complete callback.
- make sure to deactivate urbs before starting streams.

AC97 Codec Core
- added new patch codes for ALC655/658.
- fixed reset wait loop in the resume phase.
- fixed resume of AD1981 multi codecs.

- fixed possible (but rare) deadlock.

VIA82xx driver
- fixed the (syntax) description of dxs_support module option.

GUS Library
Omited to remove old code

GUS Library
Fixed duplicate control IDs (PCM Playback Volume) for cards with the codec chip

USB generic driver
- added a workaround for M-Audio Audiophile USB.
- avoid async out and adaptive in if other methods are available.
- fixed the hw_constraint check for 24bit formats.

USB generic driver
- added async_unlink option.
  the default bahevior is not changed yet.
- added some comments.

I2C lib core
- fixed sleep in lock.  use mutex for the locking.

CS4236+ driver
- fixed the detection of combination of pnp and non-pnp devices.

AC97 Codec Core
Added IC Ensemble/KS Waves ID for stereo enhancement

CMIPCI driver
- set XCHGDAC bit implicitly on MC4/6 models for fixing wrong
  playback on some boards.
- removed 'Exchange DAC' control from such a model.

EMU10K1/EMU10K2 driver
Peter Zubaj <pzad@pobox.sk>:
 - disable routing from AC97 line out to front speakers.
 - AC97 ADC is used only for Mic playback and recording
 - Philips ADC is used for other analog playback and recording
  (Analog Mix Playback Volume, Analog Mix Capture Volume)
 - removes unused AC97 controls (is phone used ???)

Takashi Iwai <tiwai@suse.de>:
 - removed the duplicated IEC958 control on Dell's board.

ALSA<-OSS emulation
Fixed semantics in snd_pcm_oss_bytes() function.

Clemens Ladisch <clemens@ladisch.de>
use vmalloc instead of kmalloc for temp buffer in proc read()/write()

Opti9xx drivers
- fixed the detection of opti92x-ad1848 pnp.

OSS device core,ALSA Core

  clean up the document.
  modified by Takashi Iwai <tiwai@suse.de>

Documentation,ALSA Core
- cards_limit=1 as default instead of 8.
- cards_limit means the number of auto-loaded cards.  not limits the
  actual card numbers for manual loading (e.g. hotplug).

ALSA<-OSS emulation
