Merge tag 'mtd/fixes-for-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull MTD fixes from Miquel Raynal:
 "In the raw NAND subsystem, the major fix prevents using cached reads
  with devices not supporting it. There was two bug reports about this.

  Apart from that, three drivers (pl353, arasan and marvell) could
  sometimes hide page program failures due to their their own program
  page helper not being fully compliant with the specification (many
  drivers use the default helpers shared by the core). Adding a missing
  check prevents these situation.

  Finally, the Qualcomm driver had a broken error path.

  In the SPI-NAND subsystem one Micron device used a wrong bitmak
  reporting possibly corrupted ECC status.

  Finally, the physmap-core got stripped from its map_rom fallback by
  mistake, this feature is added back"
