Merge tag 'sound-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai: "We have touched quite a lot of files but with fewer changes at this cycle; as you can see, most of changes are trivial fixes, especially constification patches. Among the massive attacks by constification gangs, we had a few core changes (mostly for ASoC core), as well the fixes and the updates by major vendors. Some highlights: ALSA core: - Fix possible races in control API user-TLV codes - Small cleanup of PCM core ASoC: - Continued work for componentization; still half-baked, but we're certainly progressing - Use of devres for jack detection GPIOs, rather as a cleanup - Jack detection support for Qualcomm MSM8916 - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson WM8523" * tag 'sound-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (512 commits) ALSA: hda/ca0132 - Fix memory leak at error path ALSA: hda: Fix forget to free resource in error handling code path in hda_codec_driver_probe ASoC: cs43130: Fix unused compiler warnings for PM runtime ASoC: cs43130: Fix possible Oops with invalid dev_id ASoC: cs43130: fix spelling mistake: "irq_occurrance" -> "irq_occurrence" ALSA: atmel: Remove leftovers of AVR32 removal ALSA: atmel: convert AC97c driver to GPIO descriptor API ALSA: hda/realtek - Enable jack detection function for Intel ALC700 ALSA: hda: Fix regression of hdmi eld control created based on invalid pcm ASoC: Intel: Skylake: Add IPC to configure the copier secondary pins ASoC: add missing compile rule for max98371 ASoC: add missing compile rule for sirf-audio-codec ASoC: add missing compile rule for max98371 ASoC: cs43130: Add devicetree bindings for CS43130 ASoC: cs43130: Add support for CS43130 codec ASoC: make clock direction configurable in asoc-simple ALSA: ctxfi: Remove null check before kfree ASoC: max98927: Changed device property read function ASoC: max98927: Modified DAPM widget and map to enable/disable VI sense path ASoC: max98927: Added PM suspend and resume function ...
