Merge tag 'for-linus-20170116' of git://git.infradead.org/linux-mtd 

Pull MTD fixes from Brian Norris:
 "Just NAND updates from Boris:

   - avoid compiling xway NAND controller driver as a module (which
     didn't work)

   - fix tango NAND DT binding and make sure the controller is in a
     clean state at probe time

   - add dependency on HAS_IOMEM to the oxnas NAND driver

   - fix irq number validity check in the lpc32xx driver"
