[PATCH 2/4] soundwire: slave: don't init debugfs on device registration error

From: Bard Liao
Date: Mon Apr 20 2020 - 02:46:46 EST


From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

The error handling flow seems incorrect, there is no reason to try and
add debugfs support if the device registration did not
succeed. Return on error.
