[PATCH 0/4] drm: add per-connector hotplug events

[Simon Ser]

When a uevent only updates a single connector, add a CONNECTOR property
to the uevent. This allows user-space to ignore other connectors when
handling the uevent. This is purely an optimization, drivers can still
send a uevent without the CONNECTOR property.

The CONNECTOR property is already set when sending HDCP property update
uevents, see drm_sysfs_connector_status_event.

This has been tested with a wlroots patch [1].

amdgpu has been updated to use these new fine-grained uevents.
