fsl_fdt_fixup_usb_erratum uses strcmp to detect an error but then returns 'err' without it being set to an error. Calling code may not detect that an error occurred leading to a silent failure. Instead just return -EINVAL. This issue was found by Smatch. Signed-off-by: Andrew Goodbody <andrew.goodbody@linaro.org>
