4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@xxxxxxxxxx>
commit 015105b12183556771e111e93f5266851e7c5582 upstream.
Make sure to drop the references taken by of_parse_phandle() and
bus_find_device() before returning from am335x_get_phy_control().
Note that there is no guarantee that the devres-managed struct
phy_control will be valid for the lifetime of the sibling phy device
regardless of this change.
Fixes: 3bb869c8b3f1 ("usb: phy: Add AM335x PHY driver")
