3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Felipe Balbi <balbi@xxxxxx> commit 3063a12be2b07c64e9802708a19489342e64c1a3 upstream. commi 30a70b0 (usb: musb: fix obex in g_nokia.ko causing kernel panic) removed phy_power_on() and phy_power_off() calls from runtime PM callbacks but it failed to note that the driver depended on pm_runtime_get_sync() calls to power up the PHY, thus leaving some platforms without any means to have a working PHY. Fix that by enabling the phy during omap2430_musb_init() and killing it in omap2430_musb_exit().
