Hello All,
Uhm, errr.... please disregard this patch as well.
I still get it wrong.

When gadgets are composed with configfs the user must know what are the
available function names. The names are parts of usb_f_*.ko
modules' aliases. If a function is compiled as a module, the information
can be found in modules.alias file. But if a function is compiled-in,
there is no way to know the function's name.
This patch adds a sysfs attribute in libcomposite's sys directory to
show functions which are already registered. Functions which are
compiled-in will be in this list as well.
