Subject: [PATCH] media: staging: tegra-vde: add missing pm_runtime_put_autosuspend
Date: Tue,  2 Jun 2020 00:48:41 -0500	[thread overview]
Message-ID: <20200602054841.15746-1-navid.emamdoost@gmail.com> (raw)

Call to pm_runtime_get_sync increments counter even in case of
failure leading to incorrect ref count.
Call pm_runtime_put_autosuspend if pm_runtime_get_sync fails.
