Subject: Request for cherry-picks for sound (Re: [regression, 5.10.y] Bug 216861)

Greg, just in case you missed my previous post.

Could you cherry-pick the following two commits to 5.10.y and 5.15.y
stable trees?

e8444560b4d9302a511f0996f4cfdf85b628f4ca
    ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire
 
636110411ca726f19ef8e87b0be51bb9a4cdef06
    ASoC: Intel/SOF: use set_stream() instead of set_tdm_slots() for HDAudio


Thanks!

Takashi
