2009-11-10sound: pcm: record a substream's owner processClemens Ladisch
Record the pid of the task that opened a PCM substream. For sound cards with hardware mixing, this allows determining which process is associated with a specific substream's volume control. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-10sound: rawmidi: fix opened substreams countClemens Ladisch
The substream_opened field is to count the number of opened substreams, not the number of times that any substreams have been opened. Furthermore, all substreams being opened does not imply that the next open would fail, due to the possibility of O_APPEND. With this wrong check, opening a substream multiple times would succeed only if the device had more unopened substreams.

2009-11-10sound: rawmidi: fix MIDI device O_APPEND error handlingClemens Ladisch
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 broke the error handling code in rawmidi_open_priv(). If only the output substream of a RawMIDI device has been opened and if this device is then opened with O_RDWR | O_APPEND and if the initialization of the input substream fails (either because of low memory or because the device driver's open callback fails), then the runtime structure of the already open output substream will be freed and all following writes through the first handle will cause snd_rawmidi_write() to use the NULL runtime pointer.

2009-11-10sound: rawmidi: fix checking of O_APPEND when opening MIDI deviceClemens Ladisch
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 dropped the check that a substream must already have been opened with O_APPEND to be able to open it a second time. This would make it possible for a substream to be switched to append mode, which would mean that non-atomic writes would fail unexpectedly.

2009-11-10sound: rawmidi: fix double init when opening MIDI device with O_APPENDClemens Ladisch
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 moved the substream initialization code to where it would be executed every time the substream is opened. This had the consequence that any further opening would drop and leak the data in the existing buffer, and that the device driver's open callback would be called multiple times, unexpectedly.

2009-11-07ALSA: hda - Don't initialize CORB/RIRB for single_cmd modeTakashi Iwai
So far, CORB/RIRB still remains even if the driver is switched to the single_cmd mode. The specification says that this should be disabled, but I hoped this isn't the case; indeed most devices worked together with CORB/RIRB. However, Poulsbo (US15W) seems problematic with this setup, and it requires to disable CORB/RIRB when single_cmd is used. Now this patch disables CORB/RIRB initialization when the single_cmd mode is used. Also the unsolicited event is disabled because it can't work without RIRB.

2009-11-07ALSA: usb-audio: fix combine_word problemJulian Anastasov
Fix combine_word problem where first octet is not read properly. The only affected place seems to be the INPUT_TERMINAL type. Before now, sound controls can be created with the output terminal's name which is a fallback mechanism used only for unknown input terminal types. For example, Line can wrongly appear as Speaker. After the change it should appear as Line. The side effect of this change can be that users can expect the wrong control name in their scripts or programs while now we return the correct one. Probably, these defines should use get_unaligned_le16 and friends. Signed-off-by: Julian Anastasov <ja@ssi.bg> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-11-06ASoC: OMAP: Don't try to set unsupported OMAP_DMA_DATA_BURST_16 on OMAP1Janusz Krzysztofik
After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c, omap_pcm_prepare() unconditionally calls: omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16); omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16); Current implementation of those two functions found in arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at all, so they both end with BUG() on that machine. That results in ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta. The patch corrects the problem by not calling those two functions when run on OMAP1 class based machines. Created against linux-2.6.32-rc5. Tested on Amstrad Delta.

2009-10-30ALSA: sound/parisc: Move dereference after NULL testJulia Lawall
If the NULL test on h is needed in snd_harmony_mixer_init, then the dereference should be after the NULL test. Actually, there is a sequence of calls: snd_harmony_create, then snd_harmony_pcm_init, and then snd_harmony_mixer_init. snd_harmony_create initializes h, but may indeed leave it as NULL. There was no NULL test at the beginning of snd_harmony_pcm_init, so I have added one. The NULL test in snd_harmony_mixer_init is then not necessary, but in case the ordering of the calls changes, I have left it, and moved the dereference after it. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != \(x = E\|&x\) * x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
