   4 Subject: [PATCH 55/81] mtd: nand: embed an mtd_info structure into nand_chip
   5
   6 Currently all NAND controller drivers are providing both the mtd_info and
   7 nand_chip struct and then let the NAND subsystem to initialize a few
   8 things before registering the mtd instance to the MTD layer.
   9 Embed an mtd_info field into nand_chip to add some consistency to all NAND
  10 controller drivers.
  11 This change will also help factorizing boilerplate code copied in all NAND
  12 drivers.
