Re: [PATCH] soundwire: cadence: Don't overwrite msg->buf during write commands

The buf passed in struct sdw_msg must only be written for a READ, in that case the RDATA part of the response is the data value of the register.

For a write command there is no RDATA, and buf should be assumed to be const and unmodifable. The original caller should not expect its data buffer to be corrupted by an sdw_nwrite().

Applied, thanks
