Subject: drm/i915/dp: Ratelimit DP aux timeout messages
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ee686034b8b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
