[PATCH 5.19 0175/1157] ARM: OMAP2+: display: Fix refcount leak bug

[Greg Kroah-Hartman]

From: Liang He <windhl@xxxxxxx>

[ Upstream commit 50b87a32a79bca6e275918a711fb8cc55e16d739 ]

In omapdss_init_fbdev(), of_find_node_by_name() will return a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.
