Merge tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "No dramatic changes are found in this development cycle, but as usual, many commits are applied in a wide range of drivers. Most of big changes are in ASoC, where a few bits of framework work and quite a lot of cleanups and improvements to existing code have been done. The rest are usual stuff, a few HD-audio and USB-audio quirks and fixes, as well as the drop of kthread usages in the whole subsystem. Below are some highlights: ASoC: - support for stereo DAPM controls - some initial work on the of-graph sound card - regmap conversions of the remaining AC'97 drivers - a new version of the topology ABI; this should be backward compatible - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona, Intel skylake, atom-sst - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and Realtek RT5665 USB-audio: - yet another race fix at disconnection - tolerated packet size calculation for some Android devices - quirks for Axe-Fx II, QuickCam, TEAC 501/503 HD-audio: - improvement of Dell pin fixup mapping - quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic Misc: - replace all kthread usages with simple works" * tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (296 commits) ALSA: hiface: Fix M2Tech hiFace driver sampling rate change ALSA: usb-audio: Eliminate noise at the start of DSD playback.
