mtd: build failure in drivers/mtd/chips/chipreg.c / include/linux/mtd/map.h

[Jesper Juhl <jesper.juhl@gmail.com>]

Trying to build current Linus git tree (head at 
ac07860264bd2b18834d3fa3be47032115524cea) using the attached config 
file (generated by 'make randconfig') the build fails for me with :
