Subject: drm/i915: add per-output hotplug callback for KMS
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c31c4ba3437d98efa19710e30d694a1cfdf87aa5;p=linux-beck.git

drm/i915: add per-output hotplug callback for KMS

This allows each output to deal with plug/unplug events as needed.
