This series introduce to drm a way to determine if something else
except connection_status had changed during probing, which
can be used by other drivers as well. Another i915 specific part
uses this approach to determine if edid had changed without
changing the connection status and send a hotplug event.
Stanislav Lisovskiy (3):
drm: Add helper to compare edids.
drm: Introduce change counter to drm_connector
drm/i915: Send hotplug event if edid had changed.
