Subject[PATCH] drm/radeon: Fix ECS A740GM-M DVI-D EDID error flooding problem
Date
From: Thomas Reim <reimth@gmail.com>

ECS A740GM-M with ATI RADEON 2100 sends data to i2c bus
for a DVI connector that is not implemented/existent on the board.

Fix by applying extented DDC probing for this connector.

Requires [PATCH] drm/radeon: Fix Asus M2A-VM HDMI EDID error flooding problem
