Merge tag 'usb-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull more USB updates from Greg KH:
"Here are a few more straggler patches for USB for 4.8-rc1.
Most of these are for the usb-serial driver tree. All of those have
been in linux-next for a long time, but missed my previous pull
request to you.
The remaining change is to fix up a staging tree build error, due to
some USB gadget driver changes that went in. I put it in this tree as
it was for a USB driver and people are reporting the build error on
your tree.
All of these have been in linux-next for this week, and longer for the
usb-serial changes"
