[PATCH] MTD: Correct typo "MTD_DATAFLASH_VERIFY_WRITE".

[PATCH] MTD: Correct typo "MTD_DATAFLASH_VERIFY_WRITE".

[Robert P. J. Day]

Fix the misspelling to match the actual config variable defined in
drivers/mtd/devi ces/Kconfig:

config MTD_DATAFLASH_WRITE_VERIFY
        bool "Verify DataFlash page writes"
        depends on MTD_DATAFLASH

  you know, there's a *reason* i keep reporting these anomalies...

Seems correct to me, I'll put it to l2-mtd-2.6.git, thanks.

CCint David who seem to introduced this in the following commit:

commit 8c64038e4c077b2b37c6b27d0c40c77a3ddfaeef
Author: David Brownell <dbrownell@users.sourceforge.net>
Date:   Wed Aug 6 21:55:14 2008 -0700

     [MTD] make dataflash write-verify be optional

     This adds a WRITE_VERIFY Kconfig option to the DataFlash driver,
     closely mirroring the similar NAND and ONENAND options, giving
     an option to disable some code that's currently always enabled.

     Removing this step probably saves a millisecond or so per page
     when writing data, which will add up quickly since these pages
     are small (the largest is 1 KiB).  It doesn't seem to add a
     lot in terms of reliability, and wouldn't detect errors which
     crop up when transferring data to the on-chip SRAM buffer.
