The patch titled
nvidiafb: bring back generic ddc reading
has been removed from the -mm tree. Its filename was
nvidiafb-bring-back-generic-ddc-reading.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: nvidiafb: bring back generic ddc reading
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
Make nvidiafb use fb_ddc_read(). This patch was submitted before but was
reverted due to problems in a non-x86 platform. This includes a fix for that
where ddc reading is bypassed if there is no DDC bus (duh).
