Merge tag 'upstream-4.7-rc5' of git://git.infradead.org/linux-ubifs
Pull UBI/UBIFS fixes from Richard Weinberger: "This contains fixes for two critical bugs in UBI and UBIFS: - fix the possibility of losing data upon a power cut when UBI tries to recover from a write error - fix page migration on UBIFS. It turned out that the default page migration function is not suitable for UBIFS" * tag 'upstream-4.7-rc5' of git://git.infradead.org/linux-ubifs: UBIFS: Implement ->migratepage() mm: Export migrate_page_move_mapping and migrate_page_copy ubi: Make recover_peb power cut aware gpio: make library immune to error pointers gpio: make sure gpiod_to_irq() returns negative on NULL desc gpio: 104-idi-48: Fix missing spin_lock_init for ack_lock
