Subject: [PATCH] media: mtk-jpeg: Fix a reference count leak.
Date: Sat, 13 Jun 2020 18:08:43 -0500 [thread overview]
Message-ID: <20200613230843.14109-1-wu000273@umn.edu> (raw)
From: Qiushi Wu <wu000273@umn.edu>
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus call pm_runtime_put_noidle()
if pm_runtime_get_sync() fails.
Fixes: b2f0d2724ba4 ("[media] vcodec: mediatek: Add Mediatek JPEG Decoder Driver")
Signed-off-by: Qiushi Wu <wu000273@umn.edu>
