pinctrl: SPEAr: Update error check for unsigned variables
Checking '< 0' for unsigned variables always returns false. For error codes, use IS_ERR_VALUE() instead. Signed-off-by: Tushar Behera <tushar.behera@linaro.org> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
