FR: Available function list

[NekoCWD]

I think it would be great if library could provide full list of functions, that can be used in gadget.
Maybe something like:
int *usbg_get_available_function_types()
Which will return null-terminated array of functions or error(f.e if modules directory doesn't contain modules.{order/builtin})

We can search in modules.order and modules.builtin for kernel/drivers/usb/gadget/function/usb_f_{function_name}.ko and then recognize it with usbg_lookup_function_type(function_name)
Are there better ways to do this?
If no, i can make a PR with it

I think this potential feature requires input from the Linux kernel USB community, they might have some ideas about how it should be done. Could you send a mail to the linux-usb mailing list about this? ***@***.*** http://www.linux-usb.org/mailing.html https://lore.kernel.org/linux-usb/ Please post the link to the lore thread back here too.
