sound fixes for 4.12-rc4

This contains the fixes for a few reported regression for HD-audio and
USB-audio.  All small, trivial, and boring.

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

Takashi Iwai (4):
      Revert "ALSA: usb-audio: purge needless variable length array"
      ALSA: usb: Fix a typo in Tascam US-16x08 mixer element
      ALSA: usb: Avoid VLA in mixer_us16x08.c
      ALSA: hda - Fix applying MSI dual-codec mobo quirk
