gpio-lynxpoint: force gpio_get() to return "1" and "0" only
Don't return the IN_LVL_BIT directly, a high gpio line returned value "1073741824" intestead of "1" because IN_LVL_BIT is BIT(30) Tested-by: Jerome Blin <jerome.blin@intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
