Pull mtd fixes from Miquel Raynal:
 "Four minor fixes for NAND controller drivers (cleanup path, double
  actions, and W=1 warning) as well as a cast to avoid overflows in an
  mtd device driver"

* tag 'mtd/fixes-for-6.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux:
  mtd: rawnand: omap2: Fix build warnings with W=1
  mtd: rawnand: arasan: Fix missing de-registration of NAND
  mtd: rawnand: arasan: Fix double assertion of chip-select
  mtd: diskonchip: Cast an operand to prevent potential overflow
  mtd: rawnand: fix double free in atmel_pmecc_create_user()
