I'm having trouble applying this one. For the life of me, I can't figure
out where you got this context from. This block only appears much later
in nand_scan_tail()...

Do you think you could post a git tree with your intended changes? I may
just try to pull something in like that instead.

BTW, I'm not sure the OMAP refactorings are going to come in time, but I
was planning to pull those directly from the TI folks (i.e., they won't
be rebased on l2-mtd.git), since there's some intermingling of platform
changes there. I think I can fix the conflicts fine, but FYI.
