From 0b2443ed4e07d7973e4554a2cc166bc35447b59e Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Thu, 9 Aug 2012 11:25:51 -0400 Subject: drm/edid: limit printk when facing bad edid Limit printing bad edid information at one time per connector. Connector that are connected to a bad monitor/kvm will likely stay connected to the same bad monitor/kvm and it makes no sense to keep printing the bad edid message.
