[GIT PULL] MTD changes for 3.13

Hi Linus,

David Woodhouse has given me the go-ahead to send the MTD pull request
for 3.13. Please take these fixes.

I've noted the highlights, and there are a few bits that are worth a
review (minor amendments to ABI; I don't want to hide them, but I also
think they are justified and safe).

Brian

  mtd: gpmi: fix the NULL pointer (2013-11-12 10:17:57 -0800)

----------------------------------------------------------------
MTD merge for 3.13

 * Unify some compile-time differences so that we have fewer uses of
   #ifdef CONFIG_OF in atmel_nand
 * Other general cleanups (removing unused functions, options, variables,
   fields; use correct interfaces)
 * Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via
   ONFI
 * Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.)
 * Improve differentiation between SLC and MLC NAND -- this clarifies an ABI
   issue regarding the MTD "type" (in sysfs and in ioctl(MEMGETINFO)), where
   the MTD_MLCNANDFLASH type was present but inconsistently used
 * Extend GPMI NAND to support multi-chip-select NAND for some platforms
 * Many improvements to the OMAP2/3 NAND driver, including an expanded DT
   binding to bring us closer to mainline support for some OMAP systems
 * Fix a deadlock in the error path of the Atmel NAND driver probe
 * Correct the error codes from MTD mmap() to conform to POSIX and the Linux
   Programmer's Manual. This is an acknowledged change in the MTD ABI, but I
   can't imagine somebody relying on the non-standard -ENOSYS error code
   specifically. Am I just being unimaginative? :)
 * Fix a few important GPMI NAND bugs (one regression from 3.12 and one
   long-standing race condition)
 * More? Read the log!
