Subject: [PATCH v1 1/4] media: staging: tegra-vde: Balance runtime PM use-count on resume failure
Date: Fri, 15 May 2020 00:08:44 +0300 [thread overview]
Message-ID: <20200514210847.9269-2-digetx@gmail.com> (raw)
In-Reply-To: <20200514210847.9269-1-digetx@gmail.com>
The RPM's use-count is getting incremented regardless of
pm_runtime_get_sync() success or fail. It's up to a driver how to
handle the failed RPM. In the case of VDE driver, the RPM's use-count
should be restored if runtime-resume fails.
