[PATCH v3 6/6] i915/display/dp: send a more fine-grained link-status uevent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When link-status changes, send a hotplug uevent which contains the
connector and property ID. That way, user-space can more easily
figure out that only the link-status property of this connector has
been updated.
