commit b241d31ef2f6a289d33dcaa004714b26e06f476f upstream.
Otherwise rmmod omap2430; rmmod phy-twl4030-usb; modprobe omap2430 will try to use a non-existing phy and oops:
Unable to handle kernel paging request at virtual address b6f7c1f0 ... [<c048a284>] (devm_usb_get_phy_by_node) from [<bf0758ac>] (omap2430_musb_init+0x44/0x2b4 [omap2430]) [<bf0758ac>] (omap2430_musb_init [omap2430]) from [<bf055ec0>] (musb_init_controller+0x194/0x878 [musb_hdrc])
