Merge tag 'arm-fixes-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 

Pull ARM SoC fixes from Arnd Bergmann:
 "This is one set of fixes for the NXP/FSL DPAA2 drivers, addressing a
  few minor issues. I received these just after sending out the last
  v5.15 fixes, and nothing in here seemed urgent enough for a quick
  follow-up"
