How to test if an I/O driver is installed

How can I test if a particular IO driver is installed, using it's name?

In one part of my code may do _io_xxx_install(), and elsewhere I need to test if kernel has that driver available.


I see in _io_fopen(), there is code which iterates over the IO driver list until a driver name is a match. But I can't find if there is a standalone function which would just do this in similar (or better ..) way.
