From 16bff572cc660f19e58c99941368dea050b36a05 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 28 Nov 2018 23:12:34 +0100 Subject: [PATCH] drm/dp-mst-helper: Remove hotplug callback When everyone implements it exactly the same way, among all 4 implementations, there's not really a need to overwrite this at all. Aside: drm_kms_helper_hotplug_event is pretty much core functionality at this point. Probably should move it there.
