Merge tag 'usb-serial-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-next
Johan writes:
USB-serial updates for v3.19-rc1
These changes add a new "simple" driver for Google USB-serial
devices and add support for Huawei Gobi modems to qcserial.
Included are also some removals of unnecessary atomic allocations and
a few spelling fixes.
