From 11e686855c81c2e5e647b3dcfabd2a4e473c46f0 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 23 Oct 2012 18:23:38 +0000 Subject: [PATCH] drm: don't poll forced connectors Otherwise if the detect callback reports a different state than what the user forced (rather likely), we continously annoy userspace about a hotplug uevent.
