I not see warning per my build:
"
*** Default configuration is based on 'defconfig'
#
# No change to .config
#
  CALL    scripts/atomic/check-atomics.sh
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  DTC     arch/arm64/boot/dts/freescale/imx8ulp-evk.dtb
"
Anyway I will check and fix if the node needs a fix.

Thanks,
Peng
