Merge tag 'for-linus-20121219' of git://git.infradead.org/linux-mtd
Pull MTD updates from David Woodhouse:
- Various cleanups especially in NAND tests
- Add support for NAND flash on BCMA bus
- DT support for sh_flctl and denali NAND drivers
- Kill obsolete/superceded drivers (fortunet, nomadik_nand)
- Fix JFFS2 locking bug in ENOMEM failure path
- New SPI flash chips, as usual
- Support writing in 'reliable mode' for DiskOnChip G4
- Debugfs support in nandsim
