From: Yu Kuai <yukuai3@xxxxxxxxxx> [ 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 <yukuai3@xxxxxxxxxx> Signed-off-by: Hans Verkuil <hverkuil-cisco@xxxxxxxxx> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c b/drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c index 01e680ede9bd5..f9bbd0000bf3e 100644 --- a/drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c +++ b/drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c @@ -86,6 +86,7 @@ put_device: void mtk_vcodec_release_dec_pm(struct mtk_vcodec_dev *dev) { pm_runtime_disable(dev->pm.dev); + put_device(dev->pm.larbvdec); } void mtk_vcodec_dec_pw_on(struct mtk_vcodec_pm *pm) -- 2.27.0
