Merge tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman:
"Here's the big USB pull request for 3.10-rc1.
Lots of USB patches here, the majority being USB gadget changes and
USB-serial driver cleanups, the rest being ARM build fixes / cleanups,
and individual driver updates. We also finally got some chipidea
fixes, which have been delayed for a number of kernel releases, as the
maintainer has now reappeared.
All of these have been in linux-next for a while"
