[alsa-devel] [PATCH 5/6] soundwire: stream: fix support for multiple Slaves on the same link

Pierre-Louis Bossart pierre-louis.bossart at linux.intel.com
Wed Jan 8 18:54:37 CET 2020


From: Rander Wang <rander.wang at 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.
