Merge tag 'mtd/fixes-for-4.18-rc3' of git://git.infradead.org/linux-mtd
Pull mtd fixes from Boris Brezillon:
"NAND fixes:
- add a quirk for a bunch of broken Macronix chips
- fix nand_block_bad() when chip->ecc.read_oob() returns a positive
value encoding the number of bitflips
- fix OOB handling in the MXC driver fo V2.1 controllers
- flag the ONFI_FEATURE_ON_DIE_ECC as supported in the Micron driver
- hardcode clk rate in the denali_dt driver to address a bad DT
representation (the proper fix will be queued for 4.19)
SPI NOR fixes:
- add an ULL constant to some ID definitions so that the ID is not
truncated on 32-bit platforms
MTD fixes:
- fix the sector unlocking logic in the CFI driver"
* tag 'mtd/fixes-for-4.18-rc3' of git://git.infradead.org/linux-mtd:
