gpu: ipu-v3: ipu-dmfc: Protect function ipu_dmfc_init_channel() with mutex To avoid race condition issue, we should protect the function ipu_dmfc_init_channel() with the mutex dmfc->priv->mutex, since it configures the register DMFC_GENERAL1 at runtime which contains several control bits for various display channels. This matches better with fine grained locking logic in upper layer. Signed-off-by: Liu Ying <gnuiyl@gmail.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
