From c271809eb4a52643cb5618678c81d682c20ad501 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 7 Oct 2011 14:23:47 -0400 Subject: [PATCH] drm/radeon/kms: bail early in dvi_detect for digital only connectors commit 5f0a26128d66ef81613fe923d5c288942844ccdc upstream. DVI-D and HDMI-A are digital only, so there's no need to attempt analog load detect. Also, skip bail before the !force check, or we fail to get a disconnect events. The next patches in the series attempt to fix disconnect events for connectors with analog support (DVI-I, HDMI-B, DVI-A).
