Subject: phy: twl4030-usb: remove incorrect pm_runtime_get_sync() in probe function.
From: NeilBrown <[email protected]>
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.
