Merge tag 'for-linus-20140127' of git://git.infradead.org/linux-mtd

Pull MTD updates from Brian Norris:
 - Add me (Brian Norris) as an additional MTD maintainer (it'd be nice to get
   David's "ack" for this; I'm sure he approves, but he's been pretty silent
   lately)
 - Add Ezequiel Garcie as maintainer for the pxa3xx NAND driver
 - Last (?) round of pxa3xx improvements for supporting Armada 370/XP
 - Typical churn in driver boilerplate (OOM messages, printk()'s, devm_*, etc.)
 - Quad read mode support for SPI NOR driver (m25p80)
 - Update Davinci NAND driver to prepare for use on new platforms
 - Begin to kill off NAND_MAX_{PAGE,OOB}SIZE macros; more work is pending
 - Miscellaneous NAND device support (new IDs)
 - Add READ RETRY support for Micron MLC NAND
 - Support new GPMI NAND ECC layout device-tree binding
 - Avoid mapping stack/vmalloc() memory for GPMI NAND DMA
