IMHO this is pretty fragile in the long term. For example only due to
historical reasons qualcomm wireless drivers currently under ath
directory but who knows if at some point we switch using qcom (or
qualcomm) directory. Also the wireless drivers might easily have
filenames containing strings like "msm" or "qcom" (which I assume would
match with "N" rules above).
