Merge tag 'mtd/fixes-for-7.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd fixes from Miquel Raynal:
"Besides an out-of-bound bug, this is about properly supporting Winbond
octal SPI NAND chips which use a specific pattern for stuffing more
address bits in some operations. This uses the spi-mem flag in SPI
NAND that was added to the spi-mem layer just before the merge window
through the spi tree"
