Re: [PATCH] soundwire: stream: Fix test for DP prepare complete

In sdw_prep_deprep_slave_ports(), after the wait_for_completion() the DP prepare status register is read. If this indicates that the port is now prepared, the code should continue with the port setup. It is irrelevant whether the wait_for_completion() timed out if the port is now ready.

The previous implementation would always fail if the wait_for_completion() timed out, even if the port was reporting successful prepare.

This patch also fixes a minor bug where the return from sdw_read() was not checked for error - any error code with LSBits clear could be misinterpreted as a successful port prepare.

Applied, thanks
