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).
