So you don't even compile your patches? That is bad.

The patches sent to linux-wireless should be properly tested. In some
trivial cases a compilation test might enough, but even then that needs
to be clearly documented with "Compile tested only" in the commit log.

I'm getting worried how frequent it has become that people submit
untested patches or that they test them using simulation tools like
syzbot, but not on real hardware.
