Manually? Sure there must be some way of auto do it.
Perhaps, parsing Makefile or (if we have access to a build)
use foo.ko files.

I wonder why we don't have a standardized way of naming drivers, yet.
Something like MODULE_AUTHOR, called MODULE_NAME.

(Yes, I realize it won't work if the driver is built-in)
