[PATCH] gpu: drm: mcde: add missing of_node_put before return

From: Qing Wang
Date: Mon Dec 13 2021 - 04:49:23 EST


From: Wang Qing <wangqing@xxxxxxxx>

Fix following coccicheck warning:
WARNING: Function "for_each_available_child_of_node"
should have of_node_put() before return.

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
