Why is it false positive? IMHO unless it involves a driver_override it
is a bug to fix. So have you considered tainting on driver_override
instead of bind/unbind? You did, I'm sure because several peoplel voiced
that approach already, but unless I missed something, you didn't share
your thoughts about it yet.

would be a suitable thread to share your opinion.

Best regards
