drm/radeon: Extended DDC Probing for Toshiba L300D Radeon Mobility X1100 HDMI-A Connector
commit f2b60717e692550bf753a5d64a5b69ea430fc832 upstream.
Toshiba Satellite L300D with ATI Mobility Radeon X1100 sends data
to i2c bus for a HDMI connector that is not implemented/existent
on the notebook's 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 Toshiba Satellite L300D notebook
