Merge branch 'for-linus' into for-next

Merge back for-linus branch for the badness table adjustment for VIA codecs

* for-linus:
  ALSA: hda - Fix DAC assignment for independent HP
  ALSA: hda - Fix abuse of snd_hda_lock_devices() for DSP loader
  ALSA: hda - Fix typo in checking IEC958 emphasis bit
  ALSA: snd-usb: mixer: ignore -EINVAL in snd_usb_mixer_controls()
  ALSA: snd-usb: mixer: propagate errors up the call chain
  ALSA: usb: Parse UAC2 extension unit like for UAC1
  ALSA: hda - Fix yet missing GPIO/EAPD setup in cirrus driver
ALSA: hda - Allow codec drivers to give own badness tables

The standard badness values don't seem to fit to all preferences.
Some configuration prefer the side output over the headphone, some
want the speaker over the surround, etc.

This patch moves the badness table pointers into hda_gen_spec, so that
the codec driver can override them.

ALSA: hda - Lower the badness for independent HP penalty

The lack of independent HP mode shouldn't be too bad, but currently
its badness is set a bit too high.  Let's lower it.

ALSA: hda - VIA prefers side surrounds over HP

The recent fix for the independent HP reduced the availability of the
side surround output, because there are only 4 DACs for 7.1 and a HP
outputs.  Adjust the badness tables for VIA so that 7.1 outputs are
activated for the cost of missing independent HP.

Once when we implement the dynamic DAC switching to multiple outputs,
this conflicts will be eased in future...
