[ Upstream commit 3c85234b979af71cb9db5eb976ea08a468415767 ]
of_find_matching_node() returns a device_node with refcount incremented.
Use __free(device_node) attribute to automatically call of_node_put()
when the variable goes out of scope, preventing the refcount leak.
Fixes: cabff60ca77d ("cache: Add StarFive StarLink cache management")
