I often see folks mis-running selftests, even thougggh in theory it
should be easy. And so I've added initial kernel selftests support to kdevops:

https://github.com/linux-kdevops/kdevops

So try to enable the selftests dedicated workflow, enable the firmware
test, enable building a linux-next kernel and go to town:

make menuconfig
make
make linux # installs linux-next
make selftests # builds selftests
make selftests-firwmare # runs the selftests for firmware

I think we have to up our timeout now for the firmware loader as its
currently failing as the tests now take a bit too long. Anyone oppose we
bump the firmware selftests to 200s ?
