media: mtk-vcodec: Release device nodes in mtk_vcodec_init_enc_pm()
[ Upstream commit 8ea0f2ba0fa3f91ea1b8d823a54b042026ada6b3 ] of_parse_phandle() returns the device node with refcount incremented. There are two nodes that are used temporary in mtk_vcodec_init_enc_pm(), but their refcounts are not decremented. The patch adds one of_node_put() and fixes returning error codes.
