The thing is completely wrong. They created a gadget where you can remove and add functions through sysfs. What me and Sebastian as trying to achieve with the gadget configfs interface, is get rid of all gadget drivers (nokia.c, zero.c, file_storage.c, etc) and keep only function drivers (f_*.c) in the kernel. Then the entire gadget/configuration/interface binding will be done through userland allowing any type of functions mix ups you can think of without having to add yet another my_new_gadget_with_a_slightly_different_function.c driver to the kernel tree. Android gadget was simply renamed to ccg and they sneaked into the kernel through the staging tree. That's a little unfair provided I was against the driver for several reasons. But that's fine, we can learn to live with that. -- balbi
