Merge git://git.infradead.org/mtd-2.6
* 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
