This reverts commit 95b80bf3db03c2bf572a357cf74b9a6aefef0a4a ("mdio_bus:
Remove unneeded gpiod NULL check"), this commit assumed that GPIOLIB
checks for NULL descriptors, so it's safe to drop them, but it is not
when CONFIG_GPIOLIB is disabled in the kernel. If we do call
gpiod_set_value_cansleep() on a GPIO descriptor we will issue warnings
coming from the inline stubs declared in include/linux/gpio/consumer.h.

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.
