drm/radeon: Extended DDC Probing for ECS A740GM-M DVI-D Connector
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: Extended DDC Probing for Connectors
with Improperly Wired DDC Lines
Tested for kernel 2.6.38 on Asus ECS A740GM-M board
