Subject: arm: arch_timer: balance device_node refcounting
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2b55d10c46815d9660c0f1bc6044f7019ff384aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm: arch_timer: balance device_node refcounting

When we get the device_node for the arch timer, it's refcount is
automatically incremented in of_find_matching_node, but it is
never decremented.

This patch decrements the refcount on the node after we're finished
using it.
