Hi everyone,

This patch add support for the Wii U / Nintendo Switch GameCube adapter
This is also my first contribution to the linux kernel

I tried as my best to make it based on github.com/ToadKing/wii-u-gc-adapter and
Dolphin Emulator project as well as the xpad driver.

There still an issue with it as the device report itself as an usb-hid device
the usb-hid generic driver take the priority rather than this module if usb-hid
is compiled directly into the kernel and this module as an external module.
How can I fix this problem ? The module function properly if bind manually or
if the usb-hid module is not enabled.

Also I'm not really good with parallel programming I tried my best to make sure
than there is no race condition but would be grateful if some can check too.

Thank you for your time reading my contribution
Robin
