Alright, I read-things to quickly, and to be clear:
(a) "ASoC: rt5677: Hide platform data in the module sources" is _not_ in
Linus' tree (I confused this with a different commit) and _is_ in Mark's
ASoC for-next branch currently.
(b) Applying just that patch on top of Linus' tree _does_ fix my
regression (an Oops and non-functional audio) with audio and now sound
works well, as expected.

Can we please get that as a fix for this release?  Thanks!
