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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
