[PATCH] Convert snd-page-alloc proc file to use seq_file

2007-10-17T19:30:28Z

Use seq_file for the proc file read/write of snd-page-alloc module. This automatically fixes bugs in the old proc code. Signed-off-by: Takashi Iwai Signed-off-by: Linus Torvalds

[PATCH] ALSA: Fix sysfs breakage

2007-01-29T22:32:53Z

The recent change for a new sysfs tree with card* object breaks the /sys/class/sound tree if CONFIG_SYSFS_DEPRECATED is enabled. The device in each entry doesn't point the correct device object: /sys/class/sound ... |-- pcmC0D0c | |-- dev | |-- device -> ../../../class/sound/card0 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent Also, this change breaks some drivers (like sound/arm/*) referring card->dev directly to obtain the device object for memory handling. This patch reverts the semantics of card->dev to the former version, which points to a real device object. The card* object is stored in a new card->card_dev field, instead. The device parent is chosen either card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to keep the tree compatibility. Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled. The reason of card* object is a root of all beloing devices, and it makes little sense if each sound device points to the real device object directly.

[ALSA] sound: fix PCM substream list

2006-12-20T07:56:00Z

If snd_pcm_new_stream() fails to initalize a substream (if snd_pcm_substream_proc_init() returns error), snd_pcm_new_stream() immediately return without unlinking that kfree()d substram. It causes oops when snd_pcm_free() iterates the list of substream to free them by invalid reference. Signed-off-by: Akinobu Mita Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] sound: initialize rawmidi substream list

2006-12-20T07:55:59Z

If snd_rawmidi_new() failed to allocate substreams for input (snd_rawmidi_alloc_substreams() failed to populate a &rmidi->streams[SNDRV_RAWMIDI_STREAM_INPUT]), it will try to free rawmidi instance by snd_rawmidi_free(). But it will cause oops because snd_rawmidi_free() tries to free both of substreams list but list for output (&rmidi->streams[SNDRV_RAWMIDI_STREAM_OUTPUT]) is not initialized yet.

[ALSA] Fix races in PCM OSS emulation

2006-12-20T07:55:54Z

Fixed the race among multiple threads accessing the OSS PCM instance concurrently by simply introducing a mutex for protecting a setup of the PCM. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] sound/core/control.c: remove dead code

[ALSA] pcm core: fix silence_start calculations

2006-12-20T07:55:43Z

The case where silence_size < boundary was broken because different parts of the snd_pcm_playback_silence() function disagreed about whether silence_start should point to the start or to the end of the buffer part to be silenced. This patch changes the code to always use to the start, which also simplifies several calculations. Signed-off-by: Clemens Ladisch Signed-off-by: Jaroslav Kysela

[PATCH] getting rid of all casts of k[cmz]alloc() calls

2006-12-13T17:05:58Z

Run this: #!/bin/sh for f in $(grep -Erl "$[^$]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?$[^$]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.
