Subject: [PATCH v2] soundwire: bus: provide correct return value on error

From: Bard Liao <yung-chuan.liao@...ux.intel.com>

It seems to be a typo. It makes more sense to return the return value
of sdw_update() instead of the value we want to update.

v2: address Vinod's comment and use single return
