4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: NeilBrown <neil@brown.name>
commit 4724e27114c4a7eceeee07db227a17fcab6f165c upstream.
The USB phy should initialize with power-off, and will be powered on by the USB system when a cable connection is detected.
Having this pm_runtime_get_sync() during probe causes the phy to *always* be powered on. Removing it returns to sensible power management.
