The last/only user of the chip->write_page() hook (the Atmel NAND
controller driver) has been reworked and is no longer specifying a custom
->write_page() implementation.
Drop this hook before someone else start abusing it.

Just a minor comment.


/**
 * nand_write_page - [REPLACEABLE] write one page
 * @mtd: MTD device structure


Can you update the comment block for nand_write_page(), too?

  [REPLACEABLE]  ->  [INTERNAL]

I think I'll just drop it, it does not mean anything to flag a static
function as replaceable (the ->write_page() method could be overloaded,
but not the nand_write_page() implementation itself).

Sounds good to me.   Thank you!
