Subject: [PATCH] ARM: OMAP2+: display: Fix refcount leak bug
Git-commit: 50b87a32a79bca6e275918a711fb8cc55e16d739
Patch-mainline: v6.0-rc1
References: git-fixes
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.
