Merge tag 'xceiv-for-v3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
