[PATCH 0/5] Fix deadlock on runtime suspend in DRM drivers
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,
