3.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx> commit 13518673f1419f2667985a6fca4543e44143408b upstream. The reset_gpio member of the usb_phy_gen_xceiv_platform_data structure needs the have negative value or phy-generic's probe will fail unless DT is used. 0 is a valid gpio number. This fixes an issue where phy-generic fails to probe with message: "usb_phy_gen_xceiv.0: Error requesting RESET GPIO 0".
