From: Zihao Tang <tangzihao1@xxxxxxxxxxxxx> Fix the following smatch warnings: drivers/usb/host/ohci-hcd.c:1318 ohci_hcd_mod_init() warn: ignoring unreachable code. platform_driver_register(&TMIO_OHCI_DRIVER) is the last platform_driver_register() call in ohci_hcd_mod_init(), so if it failed, there's no need to unregister it, but just goto error_tmio. So remove the unreachable platform_driver_unregister(&TMIO_OHCI_DRIVER). No functionality change.
