drm/radeon: Extended DDC Probing for Toshiba L300D Radeon Mobility X1100 HDMI-A Connector
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 BugLink: http://bugs.launchpad.net/bugs/826677 Signed-off-by: Thomas Reim <reimth@gmail.com> Acked-by: Chris Routh <routhy@gmail.com> Cc: <stable@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
