Merge tag 'for-linus-20130301' of git://git.infradead.org/linux-mtd
Pull MTD update from David Woodhouse:
"Fairly unexciting MTD merge for 3.9:
- misc clean-ups in the MTD command-line partitioning parser
(cmdlinepart)
- add flash locking support for STmicro chips serial flash chips, as
well as for CFI command set 2 chips.
- new driver for the ELM error correction HW module found in various
TI chips, enable the OMAP NAND driver to use the ELM HW error
correction
- added number of new serial flash IDs
- various fixes and improvements in the gpmi NAND driver
- bcm47xx NAND driver improvements
- make the mtdpart module actually removable"
