Yes I see but how this could help with current situation? Ho you then
specify device number?
This patch is fixing 3.13-rcx regression.

If you run grep for musb-hdrc :
arch/arm/mach-omap2/board-3430sdp.c: usb_bind_phy("musb-hdrc.0.auto",
0, "twl4030_usb");
arch/arm/mach-omap2/board-devkit8000.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");
arch/arm/mach-omap2/board-overo.c: usb_bind_phy("musb-hdrc.0.auto", 0,
"twl4030_usb");
arch/arm/mach-omap2/board-omap3beagle.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");
arch/arm/mach-omap2/board-omap3touchbook.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");
arch/arm/mach-omap2/board-cm-t35.c: usb_bind_phy("musb-hdrc.0.auto",
0, "twl4030_usb");
arch/arm/mach-omap2/board-omap3stalker.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");
arch/arm/mach-omap2/board-omap3logic.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");
arch/arm/mach-omap2/board-2430sdp.c: usb_bind_phy("musb-hdrc.0.auto",
0, "twl4030_usb");
arch/arm/mach-omap2/board-ldp.c: usb_bind_phy("musb-hdrc.0.auto", 0,
"twl4030_usb");
arch/arm/mach-omap2/board-rx51.c: usb_bind_phy("musb-hdrc.0.auto", 0,
"twl4030_usb");
arch/arm/mach-omap2/board-omap3pandora.c:
usb_bind_phy("musb-hdrc.0.auto", 0, "twl4030_usb");

Until mentioned patch isn't merged and PHY_CONSUMER isn't updated I
think this is correct solution.
