2008-11-18T17:27:58+00:00

Do not ignore the return of 'device_create_file' in
'snd_card_register' and thereby fixing the following warnings:

sound/core/init.c: In function 'snd_card_register':
sound/core/init.c:640: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result
sound/core/init.c:641: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result

ALSA: add /sys/class/sound/card#/id (r/w) and card#/number (r/o) files

2008-11-12T14:55:44+00:00

For udev, we need a way to rename soundcard names. The soundcard numbers
(indexes) are hardwired but we have a text identification which can be
changed at run-time. The ALSA user space tools already allow using of
this text identification.

saner FASYNC handling on file close

2008-11-01T16:49:46+00:00

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.

So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set.  And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

device create: sound: convert device_create_drvdata to device_create

2008-10-16T16:24:44+00:00

Now that device_create() has been audited, rename things back to the
original call to be sane.

device create: sound: convert device_create to device_create_drvdata

2008-07-22T04:54:44+00:00

device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.

[ALSA] Improve the slots option handling

2008-05-28T13:14:32+00:00

Fix and improve the slots option handling.  The sound core tries to
find the slot with the given module name first and assign if it's
still available.  If all pre-given slots are unavailable, then try
to find another free slot.

Also, when a module name begins with '!', it means the negative match:
the slot will be given for any modules but that one.

[ALSA] Clean up snd_card_free*()

2008-04-24T10:00:39+00:00

A little clean up of snd_card_free*().
Removed snd_card_free_prepare() since it's actually almost identical
with snd_card_disconnect().

[ALSA] Fix the race of card instance unregistration

2008-04-24T10:00:39+00:00

Move the call of device_unregister() for the card instance in
snd_card_disconnect() to avoid the race of sysfs card entry, which
can be typically found on usb-audio reconnection.
