This Android gadget includes a bunch of .c files. Fixing normal gadgets is not the real problem but this gadget is not always fixable since the problem here are fundumential / design. *I* wanted to get this removed but other people want to keep it even though there were reports that Android itself is not using it. Some poeple think that it is better to have this instead of nothing and other argue that they need sdb and mass storage gadget. The sdb function is not provided by ccg so I don't see the point of this. I don't see any logical reasoning behind it and I decided that it is time for retreat. This patch brings all dependencies of ccg into staging so I can do whatever I want in drivers/usb/gadget without breaking ccg.
