2018-01-16ALSA: pcm: Fix trailing semicolonLuis de Bethencourt1-1/+1
The trailing semicolon is an empty statement that does no operation. Removing it since it doesn't do anything. Signed-off-by: Luis de Bethencourt <luisbg@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-01-15ALSA: hda - Use IS_REACHABLE() for dependency on inputTakashi Iwai2-1/+5
The commit ffcd28d88e4f ("ALSA: hda - Select INPUT for Realtek HD-audio codec") introduced the reverse-selection of CONFIG_INPUT for Realtek codec in order to avoid the mess with dependency between built-in and modules. Later on, we obtained IS_REACHABLE() macro exactly for this kind of problems, and now we can remove th INPUT selection in Kconfig and put IS_REACHABLE(INPUT) to the appropriate places in the code, so that the driver doesn't need to select other subsystem forcibly.

2018-01-15ALSA: seq: Process queue tempo/ppq change in a shotTakashi Iwai3-9/+10
The SNDRV_SEQ_IOCTL_SET_QUEUE_TEMPO ioctl sets the tempo and the ppq in a single call, while the current implementation updates each value one by one. This is a bit racy, and also suboptimal from the performance POV, as each call does re-acquire the lock and invokes the update of ALSA timer resolution. This patch reorganizes the code slightly so that we change both the tempo and the ppq in a shot. The skew value can be put into the same lock, but this is rather a rarely used feature and completely independent from the temp/ppq (it's evaluated only in the interrupt), so it's left as it was.

2018-01-15ALSA: usb-audio: Add a quirk for Nura's first gen headsetMartin Peres1-0/+48
The capture interface does not work, and the playback interface actually supports only 48kHz unlike what is advertised (44.1, 32, 22, 16, 8). The only unknown here is if there are other devices that use the same product ID, but given that this ID is currently unknown, I would assume it is specially allocated for the nura headset.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v4.16 Some more updates for v4.16, the big things here are the ST DFSDM driver and the IIO patches required to support that and even more in the neverending series of code quality improvements for x86, including Pierre's work to improve the Kconfig. The unused SN95031 driver and associated board support are also removed, they haven't been buildable for a considerable time without anyone noticing.

2018-01-12ASoC: rt5645: add fallback case for jack detection supportPierre-Louis Bossart1-1/+14
Commit 78f5605c0329 ("ASoC: rt5645: cleanup DMI matching code") did a lot of useful cleanups. This patch adds a default case to enable jack detection if there is no pdata, device property or quirk. The chosen jd-mode3 is the most common and should limit the addition of new DMI-based quirks. Existing DMI quirks which only set this mode are left as is and not removed.

2018-01-11ALSA: seq: Make ioctls race-freeTakashi Iwai2-0/+4
The ALSA sequencer ioctls have no protection against racy calls while the concurrent operations may lead to interfere with each other. As reported recently, for example, the concurrent calls of setting client pool with a combination of write calls may lead to either the unkillable dead-lock or UAF. As a slightly big hammer solution, this patch introduces the mutex to make each ioctl exclusive. Although this may reduce performance via parallel ioctl calls, usually it's not demanded for sequencer usages, hence it should be negligible.

2018-01-11ALSA: pcm: Remove yet superfluous WARN_ON()Takashi Iwai1-1/+0
muldiv32() contains a snd_BUG_ON() (which is morphed as WARN_ON() with debug option) for checking the case of 0 / 0. This would be helpful if this happens only as a logical error; however, since the hw refine is performed with any data set provided by user, the inconsistent values that can trigger such a condition might be passed easily. Actually, syzbot caught this by passing some zero'ed old hw_params ioctl. So, having snd_BUG_ON() there is simply superfluous and rather harmful to give unnecessary confusions. Let's get rid of it.
