No please don't split patches just to make a script happy :)
We can tolerate few warnings if not meaningful.
But I agree it would be better to avoid such wrong warning.

It means you allow one common subdir and exactly one non-common subdir.
I think it is too much restrictive because it makes sense
to change a shared code and several related drivers.

Thanks for working on such improvement.
