From 5d250b05918c002b63632c7db91c3c5f924c6a3b Mon Sep 17 00:00:00 2001 From: Sonika Jindal Date: Mon, 5 Oct 2015 16:43:14 +0530 Subject: [PATCH] drm/i915: Call encoder hotplug for init and resume cases For all the encoders, call the hot_plug if it is registered. This is required for connected boot and resume cases to generate fake hpd resulting in reading of edid. Removing the initial sdvo hot_plug call too so that it will be called just once from this loop.
