----------------------------------------------------------------

sound fixes for 4.9-rc6

Three trivial fixes: a regression fix for ASRock mobo, a
use-after-free fix at hot-unplug of USB-audio, and a quirk for new
Thinkpad models.

----------------------------------------------------------------

Hui Wang (1):
      ALSA: hda - add a new condition to check if it is thinkpad

Takashi Iwai (2):
      ALSA: hda - Fix mic regression by ASRock mobo fixup
      ALSA: usb-audio: Fix use-after-free of usb_device at disconnect
