Yes that is true, I did think about sending this as a fix.

Adding a fix tag would not really make any functional difference as we 
will be hitting the issue only when we enable pm runtime in codec and
SoundWire controller, so I did add this as part of pm runtime patches.

Without runtime pm the clocks are left always on, so it worked so far.
