sound fixes #2 for 4.2-final

Here are stable fixes that have been gathered since rc8: fixes for
HD-audio widget power controll regressions since 4.1, a NULL fix for
HD-audio HDMI, a noise fix for Conexant codecs and a quirk addition
for USB-Audio DSD.

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

David Henningsson (1):
ALSA: hda - Shutdown CX20722 on reboot/free to avoid spurious noises

Jurgen Kramer (1):
ALSA: usb: Add native DSD support for Gustard DAC-X20U

Markus Osterhoff (1):
ALSA: hda: fix possible NULL dereference

Takashi Iwai (2):
ALSA: hda - Check all inputs for is_active_nid_for_any()
ALSA: hda - Fix path power activation
