commit: f2b60717e692550bf753a5d64a5b69ea430fc832 From: Thomas Reim <rei...@googlemail.com> Date: Wed, 17 Aug 2011 09:03:32 +0000 Subject: [PATCH] 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.
