media: mtk-vcodec: add missing put_device() call in mtk_vcodec_release_dec_pm()

2020-12-29T12:46:53+00:00

[ Upstream commit 27c3943683f74e35e1d390ceb2e3639eff616ad6 ] 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() Fixes: 590577a4e525 ("[media] vcodec: mediatek: Add Mediatek V4L2 Video Decoder Driver") Signed-off-by: Yu Kuai Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

[ Upstream commit bbe516e976fce538db96bd2b7287df942faa14a3 ] pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. For other error paths after this call, things are the same. Fix this by adding pm_runtime_put_noidle() after 'err_runtime_disable' label. But in this case, the error path after pm_runtime_put_sync() will decrease PM usage counter twice. Thus add an extra pm_runtime_get_noresume() in this path to balance PM counter. Signed-off-by: Dinghao Liu Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin
