2006-03-22[ALSA] Fix seq_clientmgr dereferences before NULL checkEugene Teo
Modules: ALSA sequencer cptr->pool must be non-NULL there, so just the if (cptr->pool) is superfluous. Thanks Takashi. Signed-off-by: Eugene Teo <eugene.teo@eugeneteo.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2006-03-22[ALSA] return ENODEV for disconnected devicesClemens Ladisch
Modules: ALSA Core Add dummy functions that return -ENODEV for the struct file_operations of a disconnected device. Without such functions, userspace would get ENOTTY. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2006-03-22[ALSA] snd_pcm_format_name() is no longer exportedJaroslav Kysela
Modules: PCM Midlevel,USB generic driver Because snd_pcm_format_name() function is used only for informational purposes, it is no longer exported from the PCM midlevel to reduce space and dependency. usbaudio module shows only numeric value for format. Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-03-22[ALSA] semaphore -> mutex (core part)Ingo Molnar

2006-02-20[PATCH] Fix snd-usb-audio in 32-bit compat environmentJuergen Kreileder
I'm getting oopses with snd-usb-audio in 32-bit compat environments: control_compat.c:get_ctl_type() doesn't initialize 'info', so 'itemlist[uinfo->value.enumerated.item]' in usbmixer.c:mixer_ctl_selector_info() might access random memory (The 'if ((int)uinfo->value.enumerated.item >= cval->max)' doesn't fix all problems because of the unsigned -> signed conversion.)

2006-01-09[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen
This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.

2006-01-03[ALSA] seq: reorganize sequencer client numbersClemens Ladisch
Modules: ALSA sequencer Reduce the maximum possible number of global clients to 16 to make more numbers available for card clients, and allow dynamically allocated card client numbers to share the same range as application client numbers to make sure that all 32 cards can be used at the same time. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] seq: set client name in snd_seq_create_kernel_client()Clemens Ladisch
All users of snd_seq_create_kernel_client() have to set the client name anyway, so we can just pass the name as parameter. This relieves us from having to muck around with a struct snd_seq_client_info in these cases. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] seq: remove struct snd_seq_client_callbackClemens Ladisch
The fields of struct snd_seq_client_callback either aren't used or are always set to the same value, so we can get rid of it altogether. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] seq: remove superfluous fieldsClemens Ladisch
Modules: ALSA sequencer None of the fields of struct snd_seq_kernel_client was actually used, so remove them. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2006-01-03[ALSA] sound/: possible cleanupsAdrian Bunk
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 Ladisch
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 (6/6): increase maximum number of sound cardsClemens Ladisch
Modules: ALSA Core,Memalloc module,ALSA sequencer With dynamic minor numbers, we can increase the number of sound cards. This requires that the sequencer client numbers of some kernel drivers are allocated dynamically, too. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (5/6): reduce maximum number of MIDI devices per cardClemens Ladisch
Modules: ALSA sequencer,Generic drivers To allow increasing the maximum number of sound cards, we have to limit the number of sequencer clients per card because client numbers are still allocated statically. Reducing the number of clients to four limits the number of sequencer MIDI ports to 1024 per card. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (4/6): dynamic minor number allocationClemens Ladisch
Modules: ALSA Core,ALSA Minor Numbers Add an option to allocate device file minor numbers dynamically. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (3/6): store device-specific object pointers dynamicallyClemens Ladisch
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 (2/6): simplify storage of snd_minor structuresClemens Ladisch
Modules: ALSA Core Store the snd_minor structure pointers in one array instead of using a separate list for each card. This simplifies the mapping from device files to minor struct by removing the need to know about the encoding of the card number in the minor number. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (1/6): store device type in struct snd_minorClemens Ladisch
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(). Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] rawmidi: protect against invalid device number in ↵Clemens Ladisch
snd_rawmidi_info_select() Modules: RawMidi Midlevel In snd_rawmidi_info_select(), check that the device identified by the passed device number actually exists. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
