From 7ee686034b8b008f19bfd913473acffc1ad51735 Mon Sep 17 00:00:00 2001 From: Lyude Date: Wed, 22 Feb 2017 22:31:02 -0500 Subject: [PATCH] drm/i915/dp: Ratelimit DP aux timeout messages Right now this is just leaving a lot of spam in dmesg that makes real issues more difficult to debug. As well (as noted by the comment right above the DRM_DEBUG_KMS() call) this is normal behavior when there's nothing connected to the DisplayPort connector.
