Subject: [PATCH] soundwire: slave: don't init debugfs on device registration error
Git-commit: 8893ab5e8ee5d7c12e0fc1dca4a309475064473d
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
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.
