This patch doesn't fix this error. I applied Mika's patch on latest
-next-queued kernel, and this issue also exists. Like below listed:
[root@x-ivb17 ~]# dmesg | grep -i "error"
[ 4.673347] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
[ 4.677734] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
[ 4.770181] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
[ 4.772661] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
[ 4.775185] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
[ 4.777690] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up

[ 4.782871] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
I append the dmesg here, maybe it can help you.</pre>
