drivers/staging/iio/addac/adt7316.c: In function adt7316_store_update_DAC:
drivers/staging/iio/addac/adt7316.c:949:3: error: implicit declaration of
 function gpiod_set_value; did you mean gpio_set_value? [-Werror=implicit-function-declaration]
   gpiod_set_value(chip->ldac_pin, 0);

drivers/staging/iio/addac/adt7316.c: In function adt7316_setup_irq:
drivers/staging/iio/addac/adt7316.c:1807:13: error: implicit declaration of
 function irqd_get_trigger_type; did you mean devm_iio_trigger_free? [-Werror=implicit-function-declaration]
  irq_type = irqd_get_trigger_type(irq_get_irq_data(chip->bus.irq));
