For historical reasons a lot of symbols in the MSM DisplayPort driver used the generic dp_ prefix. Perform a mass-rename of those symbols to use msm_dp prefix. Basically this is a result of the following script: sed drivers/gpu/drm/msm/dp/* -i -e 's/\<dp_/msm_dp_/g' sed drivers/gpu/drm/msm/dp/* -i -e 's/"msm_dp_/"dp_/g' sed drivers/gpu/drm/msm/dp/* -i -e 's/msm_\(dp_sdp_header\|dp_sdp\)\>/\1/g' Yes, this also results in renaming of several struct fields in addition to renaming the structs and functions, but I think the simple solution is better than the more complex one.
