Fix a deadlock on hybrid graphics laptops that's been present since 2013: DRM drivers poll connectors in 10 sec intervals. The poll worker is stopped on ->runtime_suspend with cancel_delayed_work_sync(). However the poll worker invokes the DRM drivers' ->detect callbacks, which call pm_runtime_get_sync(). If the poll worker starts after runtime suspend has begun,
