I run below command, have not found above warning

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 CHECK_DTBS=y freescale/imx95-15x15-evk-pcie0-ep.dtb
  DTC [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk.dtb
  DTC     arch/arm64/boot/dts/freescale/imx-m2-pcie.dtbo
  DTC     arch/arm64/boot/dts/freescale/imx-pcie0-ep.dtbo
  OVL [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk-pcie.dtb
  OVL [C] arch/arm64/boot/dts/freescale/imx95-15x15-evk-pcie0-ep.dtb

Anything wrong?
