drm/i915: Re-arm the idle timers if the device is still busy

Browse source

Don't post a downclocking task if the device is still active when the
idle timer fires. A pathological process could queue up several seconds
worth of processing and then go to sleep, during which time the idle
timer would kick in and downclock the GPU.
