[ Upstream commit094f5c315f] imx_media_add_of_subdevs() calls of_parse_phandle() and passes the obtained node to imx_media_of_add_csi(). The passed node is used in v4l2_async_nf_add_fwnode(), which increments the refcount of the node. Therefore, while the current implementation only releases the node when imx_media_of_add_csi() fails, but should always release it. Call of_node_put() right after imx_media_of_add_csi().
