Yeah, I did go that way. intel_fb_pitch_limit() that's right above inverts the order, so I switched it keep it locally consistent.

I think I even posted the patches that do it like that. > Ah yes: https://patchwork.freedesktop.org/series/39700/ Since you posted them first, let's go with it. Patches 1-3 look good to me, can you rebase and send them to the list?
