This patch series removes the static array of MTD device pointers from
mtdcore and replaces it with an idr structure for dynamic allocation of
device numbers.  It removes MAX_MTD_DEVICES, which is now meaningless.

Patches 1-4 are unchanged from the first version.
Patch 5 was completely replaced.
Patch 6 is unchanged from the first version.
Patch 7 is new and raises the limit on block translation devices.

Ben.

Ben Hutchings (7):
  mtd: Introduce and use iteration macro for reading the MTD device
    table
  mtd: Use get_mtd_device_nm() to find named device in get_sb_mtd()
  nandsim: Define CONFIG_NANDSIM_MAX_PARTS and use it instead of
    MAX_MTD_DEVICES
  mtd: Remove unnecessary comparisons with MAX_MTD_DEVICES
  mtdblock: Dynamically allocate cache info structures
  mtd: Replace static array of devices with an idr structure
  mtd: Raise limit on block device minor numbers
