From 51cfd876ddb0ccc2645f0f35c91a7dfe314dd760 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 20 Apr 2020 02:51:15 +0800 Subject: [PATCH] soundwire: slave: don't init debugfs on device registration error [ 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.
