[PATCH 5/7] media: mtk-vcodec: add missing put_device() call in mtk_vcodec_release_dec_pm()

From: Yu Kuai
Date: Fri Oct 09 2020 - 08:34:19 EST


mtk_vcodec_release_dec_pm() will be called in two places:

a. mtk_vcodec_init_dec_pm() succeed while mtk_vcodec_probe() return error.
b. mtk_vcodec_dec_remove().

In both cases put_device() call is needed, since of_find_device_by_node()
was called in mtk_vcodec_init_dec_pm() previously.

Thus add put_devices() call in mtk_vcodec_release_dec_pm()
