patch "usb: gadget: enable super speed plus" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: gadget: enable super speed plus

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: usb: gadget: enable super speed plus

Enable Super speed plus in configfs to support USB3.1 Gen2. This ensures that when a USB gadget is plugged in, it is enumerated as Gen 2 and connected at 10 Gbps if the host and cable are capable of it.

Many in-tree gadget functions (fs, midi, acm, ncm, mass_storage, etc.) already have SuperSpeed Plus support.

Tested: plugged gadget into Linux host and saw:
