From 33acc40d00bc66f2d6e84441b6c46e03bd8acfa9 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 27 Nov 2017 15:46:27 +0100 Subject: [PATCH] of: unittest: Remove bogus overlay mutex release from overlay_data_add() overlay_data_add() never takes the special overlay mutex, so it must not be released in the error patch. Presumably the call to of_overlay_mutex_unlock() is a relic from v1 of the patch.
