Subject: [PATCH net-next v8 1/2] tools: ynl-gen: allow uapi headers in sub-dirs

From: Jakub Kicinski <kuba@...nel.org>

Binder places its headers under include/uapi/linux/android/
Make sure replace / with _ in the uAPI header guard, the c_upper()
is more strict and only converts - to _. This is likely a good
constraint to have, to enforce sane naming in enums etc.
But paths may include /.
