2011-03-11ALSA: intel8x0m: wait a bit before warm reset checkPaul Bolle
At every resume a laptop I use prints this message (at KERN_ERR level): ALSA sound/pci/intel8x0m.c:904: AC'97 warm reset still in progress? [0x2] The thing to note here is that 0x2 corresponds to ICH_AC97COLD. Ie, what seems to be happening is that the register involved indicated a warm reset for some time (as the ICH_AC97WARM bit was set) but by the time the warning is printed, and that same register is checked again, that bit is already cleared and only the ICH_AC97COLD bit is still set. It turns out a warm reset needs some time to settle, but it is currently checked right away. The test therefore fails the first time it is done and schedule_timeout_uninterruptible() will be called. Once we return from that jiffies is already (far) past end_time on this laptop, so we exit the loop, print a warning, and exit the function while the warm reset actually succeeded. A way to fix this is to call usleep_range() after writing to the register involved. A handful of tests suggest 500 usecs is a safe value. (This might punish the "finish cold reset" case, but on this laptop such a cold reset apparently never happens, so I can't say for sure.) While we're at it drop the extra single tick from end_time, as it looks rather silly. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-03-08ALSA: control: fix numid conflict check for new controlsClemens Ladisch
The purpose of the snd_ctl_hole_check() function is to find conflicts between the numerical IDs of the new control and those of any existing controls. However, it would fail to detect an existing control whose count is smaller than the new control's count and whose interval of IDs is entirely contained in the interval of the new control's IDs. To fix this, use the correct formula to detect overlapping intervals, which happens to simplify the condition. This problem was not encountered so far because ALSA does not yet allow drivers to allocate specific control IDs.

2011-02-23ALSA: usb-audio: fix oops due to cleanup race when disconnectingTakashi Iwai
When a USB audio device is disconnected, snd_usb_audio_disconnect() kills all audio URBs. At the same time, the application, after being notified of the disconnection, might close the device, in which case ALSA calls the .hw_free callback, which should free the URBs too. Commit de1b8b93a0ba "[ALSA] Fix hang-up at disconnection of usb-audio" prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that resulted from this race, but this introduced another race because the URB callbacks could now be executed after snd_usb_hw_free() has returned, and try to access already freed data. Fix the first race by introducing a mutex to serialize the disconnect callback and all PCM callbacks that manage URBs (hw_free and hw_params).

2011-02-19ALSA: azt3328: add custom AC97 semi-emulation use standard ALSA AC97 layerAndreas Mohr
Make use of the very flexible ALSA ac97 layer (hooks for custom I/O!) on this weird AC97 copycat hardware, via semi-extended I/O translation/emulation. Some 5kB binary/loaded size saved (well... additional huge AC97 module penalty not factored in, of course ;-P). Given that the driver previously had 20kB that's not bad, but the much more important thing is to have AC97 layer stress-tested with a thoroughly weird AC97 copycat (or, simply put, if it were not for this AC97 test aspect, this effort would merely have been a nut job ;).

2011-02-14ALSA: usb-audio: add support for Native Instruments MK2 devicesDaniel Mack
The MK2 generation of Native Instruments' sound cards are in fact compliant to the USB audio standard of version 2 and other approved USB standards. However, they come up as vendor-specific device when first connected but can be told to come up with a new set of descriptors upon their next enumeration. The interfaces announced by the new descriptors will be handled by the kernel's class drivers. This is done by issuing a vendor specific device request and sending the device to reset. There are also some vendor-specific USB requests for some mixer elements that can't be exported in a standard compliant way. The driver now supports them with quirks handling mechanisms.
