3.0-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Thomas Reim <rei...@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

   Tested for kernel 2.6.38 on Toshiba Satellite L300D notebook
