gpio: pcie-idio-24: Implement get_multiple/set_multiple callbacks The ACCES I/O PCIe-IDIO-24 series of devices provides 24 optically-isolated digital I/O accessed via six 8-bit ports. Since eight input lines are acquired on a single port input read -- and similarly eight output lines are set on a single port output write -- the PCIe-IDIO-24 GPIO driver may improve multiple I/O reads/writes by utilizing a get_multiple/set_multiple callbacks. This patch implements the idio_24_gpio_get_multiple function which serves as the respective get_multiple callback, and implements the idio_24_gpio_set_multiple function which serves as the respective set_multiple callback.
