The RPM's use-count is getting incremented regardless of the
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. Use pm_runtime_put_noidle(),
which is the most straight-forward variant to balance the RPM, confirmed
by Rafael J. Wysocki.
