2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2013-01-21usb: gadget: add a forward pointer from usb_function to its "instance"Sebastian Andrzej Siewior
We can have multiple usb_functions which origin is the same "instance". Within one USB configuration there should be only one function of an instance. This back pointer helps configfs to recoginze to which instance a given usb_function belongs.
