sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21+00:00

Lots of sound drivers were getting module.h via the implicit presence
of it in  but we are going to clean that up.  So
fix up those users now.

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: oss-mixer - use strlcpy() instead strcpy()

2011-10-04T06:47:52+00:00

This is mostly a static checker fix more than anything else.  We're
copying from a 64 char buffer into a 44 char buffer.

The 64 character buffer is str[] in snd_mixer_oss_build_test_all().
The call tree is:
	snd_mixer_oss_build_test_all()
	-> snd_mixer_oss_build_test()
	   -> snd_mixer_oss_build_test().

We never actually do fill str[] buffer all the way to 64 characters.
The longest string is:
	sprintf(str, "%s Playback Switch", ptr->name);
ptr->name is a 32 character buffer so 32 plus 16 characters for
" Playback Switch" still puts us over the 44 limit from "id.name".

Most likely ptr->name never gets filled to the limit, but we can't
really change the size of that buffer so lets just use strlcpy() here
and be safe.

ALSA: core: sparse cleanups

2011-02-14T16:10:11+00:00

Change the core code where sparse complains.  In most cases, this means
just adding annotations to confirm that we indeed want to do the dirty
things we're doing.

ALSA: Don't leak in sound/core/oss/pcm_oss.c::snd_pcm_hw_param_near()

2011-01-10T10:13:42+00:00

snd_pcm_hw_param_near() will leak the memory allocated to 'save' if the
call to snd_pcm_hw_param_max() returns less than zero.
This patch makes sure we never leak.

ALSA: Fix SNDCTL_DSP_RESET ioctl for OSS emulation

2010-11-30T07:18:58+00:00

In OSS emulation, SNDCTL_DSP_RESET ioctl needs the reset of the internal
buffer state in addition to drop of the running streams.  Otherwise the
succeeding access becomes inconsistent.
