| |
3.0-stable review patch. If anyone has any objections, please let us know.
------------------ From: Thomas Reim <reimth@googlemail.com>
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
