struct gpio_chip documentation recommends to always implement this callback function. A more concrete motivation is to be able (in combination with GPIOD_ASIS) to detect whether the bootloader has changed the state of a GPIO signal. Signed-off-by: Baruch Siach <baruch@tkos.co.il>
This is strongly recommended for all drivers to implment so patch applied. Yours, Linus Walleij _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
