Linus Torvalds bcb46a0e0e sound fixes for 5.2-rc5 
you might feel like a deja vu to receive a bulk of changes at rc5,
 and it happens again; we've got a collection of fixes for ASoC.
 Most of fixes are targeted for the newly merged SOF (Sound Open
 Firmware) stuff and the relevant fixes for Intel platforms.
 
 Other than that, there are a few regression fixes for the recent
 ASoC core changes and HD-audio quirk, as well as a couple of
 FireWire fixes and for other ASoC codecs.
