Well, the question is whether merging it would break other things or
not.

Currently the sound on the laptop won't work anyway, and applying this
in other tree would need the back-pull of existing HD-audio changes
from sound.git tree or Linus treee, which is often cumbersome.  The
goal is to plumb everything up in 5.17-rc as soon as possible, and
it's often faster if each tree concentrates on only the responsible
bits.
