media: platform: exynos4-is: Fix an OF node reference leak in fimc_md_is_isp_available

Browse source

commit 8964eb2340 upstream.

In fimc_md_is_isp_available(), of_get_child_by_name() is called to check
if FIMC-IS is available. Current code does not decrement the refcount of
the returned device node, which causes an OF node reference leak. Fix it
by calling of_node_put() at the end of the variable scope.
