2006-12-20[ALSA] sound: initialize rawmidi substream listAkinobu Mita1-1/+3
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.

2006-09-23[ALSA] Fix substream selection in PCM and rawmidiTakashi Iwai1-1/+2
The PCM and rawmidi substreams can be selected explicitly by opening control handle and set via *_PREFER_SUBDEVICE ioctl. But, when multiple controls are opened, the driver gets confused. The patch fixes the initialization of prefer_*_subdevice and the check of multiple controls. The first set subdevice is picked up as the valid one.

2006-09-23[ALSA] Unregister device files at disconnectionTakashi Iwai1-26/+9
Orignally proposed by Sam Revitch <sam.revitch@gmail.com>. 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 <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-09-23[ALSA] Fix disconnection of proc interfaceTakashi Iwai1-1/+1
- 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 <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-06-22[ALSA] Remove zero-initialization of static variablesTakashi Iwai1-1/+1
Removed zero-initializations of static variables. A tiny optimization. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2006-06-22[ALSA] Remove unneeded read/write_size fields in proc text opsTakashi Iwai1-1/+0
Remove unneeded read/write_size fields in proc text ops. snd_info_set_text_ops() is fixed, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2006-01-03[ALSA] sound/: possible cleanupsAdrian Bunk1-3/+2
Modules: RawMidi Midlevel,HDA generic driver This patch contains the following possible cleanups: - pci/hda/hda_proc.c should #include 'hda_local.h' for including the prototype of it's global function snd_hda_codec_proc_new() - core/rawmidi.c: make the needlessly global and EXPORT_SYMBOL'ed function snd_rawmidi_info() static Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2006-01-03[ALSA] rawmidi: adjust runtime->avail when changing output buffer sizeClemens Ladisch1-0/+1
Modules: RawMidi Midlevel When the output buffer size is changed, runtime->avail must be adjusted to the new size; otherwise, draining of a bigger buffer would appear to fail because avail does not reach buffer_size. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (3/6): store device-specific object pointers dynamicallyClemens Ladisch1-43/+44
Instead of storing the pointers to the device-specific structures in an array, put them into the struct snd_minor, and look them up dynamically. This makes the device type modules independent of the minor number encoding. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (1/6): store device type in struct snd_minorClemens Ladisch1-9/+5
Instead of a comment string, store the device type in the snd_minor structure. This makes snd_minor more flexible, and has the nice side effect that we don't need anymore to create a separate snd_minor template for registering a device but can pass the file_operations directly to snd_register_device().

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
