Subject: [PATCH 5.7 160/477] soundwire: slave: dont init debugfs on device registration error
From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>
[ Upstream commit 8893ab5e8ee5d7c12e0fc1dca4a309475064473d ]
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.
