* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: usb-audio: Use kmemdup rather than duplicating its implementation
  ALSA: hda - Re-enable the check NO_PRESENCE misc bit
  ALSA: vmaster - Free slave-links when freeing the master element
  ALSA: hda - Don't add elements of other codecs to vmaster slave
  ALSA: intel8x0: improve virtual environment detection
  ALSA: intel8x0: move virtual environment detection code into one place
  ALSA: snd_usb_audio: add Logitech HD Webcam c510 to quirk-384
  ALSA: hda - fix internal mic on Dell Vostro 3500 laptop
  ALSA: HDA: Remove quirk for Toshiba T110
  ALSA: usb-audio - Fix the missing volume quirks at delayed init
  ALSA: hda - Mute unused capture sources for Realtek codecs
  ALSA: intel8x0: Improve comments for VM optimization
  ASoC: Ensure we get an impedence reported for WM8958 jack detect
  ASoC: Don't use wm8994->control_data when requesting IRQs
  ASoC: Don't use wm8994->control_data in wm8994_readable_register()
  ASoC: Update git repository URL
