* git://git.infradead.org/mtd-2.6:
  mtd: nand: fix build failure and incorrect return from omap_wait()
  mtd: Use BLOCK_NIL consistently in NFTL/INFTL
  mtd: m25p80 timeout too short for worst-case m25p16 devices
  mtd: atmel_nand: Fix typo s/parititions/partitions/
  mtd: cmdlineparts: Use 64-bit format when printing a debug message.
  mtd: maps: Remove BUS_ID_SIZE from integrator_flash
  jffs2: fix another potential leak on error path in scan.c
