[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.

[ALSA] Fix hang-up at disconnection of usb-audio

2006-11-28T12:46:38Z

Fix hang-up at disconnection of usb-audio devices while accessing PCM. Don't handle PCM operations any more after shutdown flag is set. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Unregister device files at disconnection

2006-09-23T08:36:58Z

Orignally proposed by Sam Revitch . Unregister device files at disconnection to avoid the futher accesses. Also, the dev_unregister callback is removed and replaced with the combination of disconnect + free. A new function snd_card_free_when_closed() is introduced, which is used in USB disconnect callback. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Fix disconnection of proc interface

2006-09-23T08:36:48Z

- Add the linked list to each proc entry to enable a single-shot disconnection (unregister) - Deprecate snd_info_unregister(), use snd_info_free_entry() - Removed NULL checks of snd_info_free_entry() Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Don't reject O_RDWR at opening PCM OSS with read/write-only device

2006-08-03T13:21:31Z

Accept O_RDWR at opening a PCM OSS device that is read- or write-only, just for the compatibility with the behavior of older versions. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Fix mmap_count with O_APPEND opened streams

2006-06-22T19:33:14Z

Move mmap_count to snd_pcm_substream instead of runtime struct so that multiplly opened substreams via O_APPEND can be handled correctly. Signed-off-by: Takashi Iwai

[ALSA] Add O_APPEND flag support to PCM

2006-06-22T19:33:13Z

Added O_APPEND flag support to PCM to enable shared substreams among multiple processes. This mechanism is used by dmix and dsnoop plugins. Signed-off-by: Takashi Iwai
