I've pushed this on a branch for testing in KernelCI at

	https://linux.kernelci.org/test/job/broonie-misc/branch/for-kernelci/kernel/v5.19-rc1-50-g71b086bc92064/

It's still running, while it's not going to get great coverage of SPI
it'll get some just through initialising things a boot (and a few
ethernet controllers IIRC which do get heavily used) and it will cover a
wide variety of hardware which is pretty useful even if the coverage is
only light.
