[PATCH 4.14 055/165] usb: dwc3: Undo PHY init if soft reset fails

[Greg Kroah-Hartman]

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

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

From: Brian Norris <briannor...@chromium.org>

[ Upstream commit 00b42170c86f90ac9dea83a7dfcd3f0c38098fe2 ]

In this function, we init the USB2 and USB3 PHYs, but if soft reset
times out, we don't unwind this.

Noticed by inspection.
