Merge tag 'mtd/fixes-for-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux

Pull mtd fixes from Miquel Raynal:
 "MTD core:
   - partitions: Add missing of_node_get() in dynamic partitions code

  Parser drivers:
   - bcm47xxpart: Fix halfblock reads

  Raw NAND controller drivers:
   - marvell: Use correct logic for nand-keep-config
   - tegra: Fix PM disable depth imbalance in probe
   - intel: Add missing of_node_put() in ebu_nand_probe()

  SPI-NOR core changes:
   - Ignore -ENOTSUPP in spi_nor_init()"
