Subject: [PATCH 3.16.y-ckt 107/118] usb: gadget: mv_udc_core: fix phy_regs I/O memory leak

3.16.7-ckt16 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexey Khoroshilov <khoroshilov@...ras.ru>

commit 53e20f2eb161fbe9eea28b54dccc870cec94eca2 upstream.

There was an omission in transition to devm_xxx resource handling.
iounmap(udc->phy_regs) were removed, but ioremap() was left
without devm_.

Found by Linux Driver Verification project (linuxtesting.org).
