From: Alex Deucher Date: Fri, 7 Oct 2011 18:23:47 +0000 (-0400) Subject: drm/radeon/kms: bail early in dvi_detect for digital only connectors X-Git-Tag: v3.1.1~241 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e5edf277645a096ccdca1fe6b8ea31831c89b04a;p=thirdparty%2Fkernel%2Fstable.git 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).
