Subject: [PATCH 1/5] soundwire: qcom: return error when pm_runtime_get_sync fails

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

For some reason there's a missing error return in two places.

Fixes: 74e79da9fd46a ("soundwire: qcom: add runtime pm support")
Fixes: 04d46a7b38375 ("soundwire: qcom: add in-band wake up interrupt support")
