From 5a4dd6f0e846541e57a58f97fce86da1f3ab3a88 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 24 Aug 2022 16:15:42 +0300 Subject: [PATCH] drm/i915: move hotplug to display.hotplug Move display hotplug related members under drm_i915_private display sub-struct. Rename struct i915_hotplug to intel_hotplug while at it.
