Merge tag 'mtd/fixes-for-5.2-final' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull mtf fixes from Miquel Raynal:

 - Fix the memory organization structure of a Macronix SPI-NAND chip.

 - Fix a build dependency wrongly described.

 - Fix the sunxi NAND driver for A23/A33 SoCs by (a) reverting the
   faulty commit introducing broken DMA support and (b) applying another
   commit bringing working DMA support.

* tag 'mtd/fixes-for-5.2-final' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux:
  mtd: rawnand: sunxi: Add A23/A33 DMA support with extra MBUS configuration
  Revert "mtd: rawnand: sunxi: Add A23/A33 DMA support"
