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.

These devices use CMA (Contiguous Memory Allocator) backed graphics memory. This patch provides helper functions to be able to share the code. The code technically does not depend on CMA as the backend allocator, the name has been chosen because CMA makes for a nice, short but still descriptive function prefix.
