Merge tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH:
"Here is the big patchset of USB and PHY driver updates for 4.13-rc1.
On the PHY side, they decided to move files around to "make things
easier" in their tree. Hopefully that wasn't a mistake, but in
linux-next testing, we haven't had any reported problems.
There's the usual set of gadget and xhci and musb updates in here as
well, along with a number of smaller updates for a raft of different
USB drivers. Full details in the shortlog, nothing really major.
All of these have been in linux-next for a while with no reported
issues"
