Merge tag 'mtd/fixes-for-5.0-rc3' of git://git.infradead.org/linux-mtd
Pull mtd fixes from Boris Brezillon: "Raw NAND changes: - jz4740: fix a compilation warning - fsmc: fix a regression introduced by ->select_chip() deprecation - denali: fix a regression introduced by NAND_KEEP_TIMINGS addition" * tag 'mtd/fixes-for-5.0-rc3' of git://git.infradead.org/linux-mtd: mtd: rawnand: denali: get ->setup_data_interface() working again mtd: nand: jz4740: fix '__iomem *' vs. '* __iomem' mtd: rawnand: fsmc: Keep bank enable bit set
