Merge tag 'spi-nor/for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next
SPI NOR core changes: - Print all JEDEC ID bytes on error - Fix comment of spi_nor_find_best_erase_type() - Add region locking flags for s25fl512s SPI NOR controller drivers changes: - intel-spi: * Avoid crossing 4K address boundary on read/write * Add support for Intel Comet Lake SPI serial flash
