Merge git://git.infradead.org/mtd-2.6
* git://git.infradead.org/mtd-2.6: (97 commits) mtd: kill CONFIG_MTD_PARTITIONS mtd: remove add_mtd_partitions, add_mtd_device and friends mtd: convert remaining users to mtd_device_register() mtd: samsung onenand: convert to mtd_device_register() mtd: omap2 onenand: convert to mtd_device_register() mtd: txx9ndfmc: convert to mtd_device_register() mtd: tmio_nand: convert to mtd_device_register() mtd: socrates_nand: convert to mtd_device_register() mtd: sharpsl: convert to mtd_device_register() mtd: s3c2410 nand: convert to mtd_device_register() mtd: ppchameleonevb: convert to mtd_device_register() mtd: orion_nand: convert to mtd_device_register() mtd: omap2: convert to mtd_device_register() mtd: nomadik_nand: convert to mtd_device_register() mtd: ndfc: convert to mtd_device_register() mtd: mxc_nand: convert to mtd_device_register() mtd: mpc5121_nfc: convert to mtd_device_register() mtd: jz4740_nand: convert to mtd_device_register() mtd: h1910: convert to mtd_device_register() mtd: fsmc_nand: convert to mtd_device_register() ... Fixed up trivial conflicts in - drivers/mtd/maps/integrator-flash.c: removed in ARM tree - drivers/mtd/maps/physmap.c: addition of afs partition probe type clashing with removal of CONFIG_MTD_PARTITIONS
