Subject: ARM: EXYNOS: fix double of_node_put() on error path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3e9f798784b30293012682021d5a0352f78658b8;p=linux-beck.git

ARM: EXYNOS: fix double of_node_put() on error path

The change removes the second of_node_put(), if
for_each_compatible_node() body execution is not terminated. This
prevents from object refcounter overflow over zero in OF_DYNAMIC
build.
