regmap-sdw does not support multi register writes, so there is
no point in setting this flag. This also leads to incorrect

This invalid configuration should have been rejected by regmap-sdw.

Does the CODEC support mulitple writes? If so it seems better to leave
No, the codec itself does not support multi-write. All the codec register level interface is via SoundWire Bus. which also does not support with the existing code.


--srini

the flag set and just do the appropriate fix in the regmap code until
such time as it's updated to be able to exercise it.
