ALSA: platform: Check CONFIG_PM_SLEEP instead of CONFIG_PM

2012-08-09T13:47:15+00:00

When CONFIG_PM is set but CONFIG_PM_SLEEP is unset,
SIMPLE_DEV_PM_OPS() ignores the given functions, and this leads to
compile warnings.

For avoiding this, simply check CONFIG_PM_SLEEP instead of CONFIG_PM.

ALSA: module_param: make bool parameters really bool

2011-12-19T09:34:41+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

sound: fix drivers needing module.h not moduleparam.h

2011-10-31T23:31:19+00:00

The implicit presence of module.h lured several users into
incorrectly thinking that they only needed/used modparam.h
but once we clean up the module.h presence, these will show
up as build failures, so fix 'em now.

ALSA: dummy driver - add model parameter

2010-02-02T16:50:57+00:00

This is a cleanup for the dummy driver. The model kernel module parameter
is introduced to select the soundcard emulation.

ALSA: sound: Move dereference after NULL test and drop unnecessary NULL tests

2009-10-30T11:01:27+00:00

In pcm.c, if the NULL test on pcm is needed, then the dereference should be
after the NULL test.

In dummy.c and ali5451.c, the context of the calls to
snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice,
respectively cannot be NULL.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// 
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
  ... when != \(x = E\|&x\)
* x == NULL
//

ALSA: dummy - Increase MAX_PCM_SUBSTREAMS to 128

2009-09-08T16:15:17+00:00

Increase the limit of PCM substreams to 128.  The default value is
unchanged; only the max accept value is increased.

ALSA: dummy - Add debug proc file

2009-09-08T12:46:49+00:00

Added the debug proc file to see or change the snd_pcm_hardware fields
to emulate.  The parameters can be changed by writing to a proc file like:

    # echo periods_min 4 > /proc/asound/card1/dummy_pcm
