Merge tag 'for-linus-20121009' of git://git.infradead.org/mtd-2.6

Pull MTD updates from David Woodhouse:

 - Disable broken mtdchar mmap() on MMU systems
 - Additional ECC tests for NAND flash, and some test cleanups
 - New NAND and SPI chip support
 - Fixes/cleanup for SH FLCTL NAND controller driver
 - Improved hardware support for GPMI NAND controller
 - Conversions to device-tree support for various drivers
 - Removal of obsolete drivers (sbc8xxx, bcmring, etc.)
 - New LPC32xx drivers for MLC and SLC NAND
 - Further cleanup of NAND OOB/ECC handling
 - UAPI cleanup merge from David Howells (just moving files, since MTD
   headers were sorted out long ago to separate user-visible from kernel
   bits)
