MIPS: OCTEON: octeon-usb: Use devm_platform_get_and_ioremap_resource()
Remove unneeded error handling on the result of a call to platform_get_resource() when the value is passed to devm_ioremap_resource(). And use devm_platform_get_and_ioremap_resource() to simplify code. Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
