Subject: clk: armada-xp: fix refcount leak in axp_clk_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20e91173a0b5b3a21d8a25b790098a5ecb3dec23;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

clk: armada-xp: fix refcount leak in axp_clk_init()

[ Upstream commit db20a90a4b6745dad62753f8bd2f66afdd5abc84 ]

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
