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? -Mike
