Yes, I'm very close to applying these patches now.

Added in the pending branch.

Added these as well.

And this also. Please check that everything is ok in the pending branch
I just pushed:

These errors are because of my mistakes in the conflict resolutions I
did yesterday. They should be fixed now.

Yeah, the errors reported by kbuild bot were unrelated.

BTW, I can already use COMPILE_TEST to for compiling snoc.c on x86. I do
get some warnings about QMI_HELPERS which I guess your patches fix once

Thanks for all the help!
