Subject: linux-next: build warning after merge of the devicetree tree

Hi all,

After merging the devicetree tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

arch/arm/boot/dts/bcm2711-rpi-4-b.dts:220.10-231.4: Warning (pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format error, expected "0,0"
arch/arm/boot/dts/bcm2711-rpi-4-b.dts:220.10-231.4: Warning (pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format error, expected "0,0"

Presumably exposed by commit

1ee7943c3343 ("kbuild: Enable dtc 'pci_device_reg' warning by default")

Yep, that's expected. There's a couple on arm64 builds too.

These warnings are now in Linus' tree :-(

There's some pending patches for them now[1]. The SoC tree needs to
pick them up.
