Subject[PATCH 2/3] media: mtk-vcodec: add missing put_device() call in mtk_vcodec_init_dec_pm()
Date
if of_find_device_by_node() succeed, mtk_vcodec_init_dec_pm() doesn't have
a corresponding put_device(). Thus add jump target to fix the exception
handling for this function implementation.

Fixes: 590577a4e525 ("[media] vcodec: mediatek: Add Mediatek V4L2 Video Decoder Driver")
