Subject: [PATCH] drm:pl111: Add of_node_put() when breaking out of for_each_available_child_of_node()
Git-commit: e0686dc6f2252e009c455fe99e2ce9d62a60eb47
Patch-mainline: v6.1-rc1
References: git-fixes

The reference 'child' in the iteration of for_each_available_child_of_node()
is only escaped out into a local variable which is only used to check
its value. So we still need to the of_node_put() when breaking of the
for_each_available_child_of_node() which will automatically increase
and decrease the refcount.
