Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses. This patch adds these
identifiers to all files in drivers/usb/ based on a script and data from
Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

Unless someone really complains, I'm going to add this to my tree for
4.15-rc1.
