Hello,

Unless I'm missing something, this looks like a resend of a patchset 
from earlier this year [1]. Previous owner of the subject, Yauhen 
Kharuzhy, is not even CC'ed here. I do not see any of the review points 
addressed here, moreover, I see a regression when compared to v3 from June.

Hiding behind RFC (not v4) is a weird move when viewed in context of 
CHT. The configuration is mature, CHT is over 12 years old. With basic 
playback/capture not enabled, does the review make sense?
