linux-next: manual merge of the sound tree with the drm-intel tree

[Stephen Rothwell]

Hi Takashi,

Today's linux-next merge of the sound tree got a conflict in:

  drivers/gpu/drm/i915/intel_audio.c

between commit:

  3c85f5027595 ("drm/i915: s/mode/adjusted_mode/ in functions that really get 
passed the adjusted_mode")

from the drm-intel tree and commit:

  7e8275c2f2bb ("drm/i915: set proper N/CTS in modeset")

from the sound tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
