Great, then you can use the 'let's make a sysfs file and grep for it
from userspace' option.

Or, you can use the 'create a directory for your class, and create
symlinks in there like other subsystems do' option.

Both of which require no changes in the driver core, and have precedent
in that other subsystems already do this today.

Good luck,
