I think most gpiochips easily survives calling the .get_direction() early, Qualcomm's stand out here. Now that we have .valid_mask in the gpiochip could we simply just add this back, resepecting valid_mask and avoid checking the direction of precisely these GPIOs?
Can you be more specific? One of the proposals made previously was to add a check in msm_gpio_get_direction(), but that was rejected because the consensus was the valid_mask checks in gpiolib are sufficient.
