But it really really is bad.  Looking at gitk fork in the road leading
to it...

52d9d38c183b drm/sti:fix spelling mistake: "compoment" -> "component" - good
e4e818cc2d7c drm: make drm_panel.h self-contained                     - good
9cf8f5802f39 drm: add missing declaration to drm_blend.h              - good

Before the git highway splits, all is well.  The lane with commits
works fine at both ends, but e98c58e55f68 is busted.  Merge arfifact?
