Merge tag 'for-linus-20161104' of git://git.infradead.org/linux-mtd
Pull MTD fixes from Brian Norris: - MAINTAINERS updates to reflect some new maintainers/submaintainers. We have some great volunteers who've been developing and reviewing already. We're going to try a group maintainership model, so eventually you'll probably see pull requests from people besides me. - NAND fixes from Boris: "Three simple fixes: - fix a non-critical bug in the gpmi driver - fix a bug in the 'automatic NAND timings selection' feature introduced in 4.9-rc1 - fix a false positive uninitialized-var warning" * tag 'for-linus-20161104' of git://git.infradead.org/linux-mtd: mtd: mtk: avoid warning in mtk_ecc_encode mtd: nand: Fix data interface configuration logic mtd: nand: gpmi: disable the clocks on errors MAINTAINERS: add more people to the MTD maintainer team MAINTAINERS: add a maintainer for the SPI NOR subsystem
