Merge tag 'for-linus-20130318' of git://git.infradead.org/linux-mtd
Pull MTD fixes from David Woodhouse:
"This fixes a couple of problems. Firstly, some people are actually
still using old small-page flash and we broke it by removing the ready
check.
Secondly. fix the handling of partitions on Broadcom 47xx devices.
Recent changes had made it misdetect the location of the NVRAM and
scribble over the bootloader when it tried to update the variables
there. With predictably sad results."
