[PATCH 0/7] mtd: spi-nor: fixes found when debugging smpt

[<Tudor.Ambarus@microchip.com>]

Bunch of fixes that we found while debugging the roll back to
SPINOR_OP_READ_1_1_4_4B in case smpt parser fails.

Boris, Yogesh,

Now I'm looking for a fix in case the smpt detection commands
define variable address length and dummy bytes. Will follow.

Tudor Ambarus (7):
  mtd: spi-nor: don't drop sfdp data if optional parsers fail
  mtd: spi-nor: fix iteration over smpt array
  mtd: spi-nor: add restriction for nmaps in smpt parser
  mtd: spi-nor: don't overwrite errno in spi_nor_get_map_in_use()
  mtd: spi_nor: pass DMA-able buffer to spi_nor_read_raw()
  mtd: spi-nor: ensure memory used for nor->read() is DMA safe
  mtd: spi-nor: remove unneeded smpt zeroization
