gpio: Convert gpio_is_valid to return bool
Make the code a bit more readable. Instead of casting an int to an unsigned then comparing to MAX_NR_GPIOS, add a >= 0 test and let the compiler optimizer do the conversion to unsigned. The generated code should be the same. Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
