Subject[PATCH v2 4/5] soundwire: stream: fix support for multiple Slaves on the same link
Date
From: Rander Wang <rander.wang@intel.com>

The existing code will unconditionally return after dealing with the
first Slave on a link. This return should only happen when there is
an error case.

Tested on Comet Lake platform.
