[PATCH 4.19 046/287] ARM: OMAP2+: display: Fix refcount leak bug

From: Greg Kroah-Hartman
Date: Tue Aug 23 2022 - 06:35:15 EST


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.
