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" * tag 'arm-fixes-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: soc: fsl: dpaa2-console: free buffer before returning from dpaa2_console_read soc: fsl: dpio: use the combined functions to protect critical zone soc: fsl: dpio: replace smp_processor_id with raw_smp_processor_id
