This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit c69dbbf3335a21aae74376d7e5db50a486d52439 upstream.
Instead of writing to "nand->reg + REG_FMICSR" we write to "REG_FMICSR"
which is NULL and not a valid register.
Fixes: 8bff82cbc308 ('mtd: add nand support for w90p910 (v2)')
