[ Upstream commit9b97123a58] The newly added runtime-pm support causes a harmless warning when CONFIG_PM is disabled: drivers/net/phy/mdio-bcm-unimac.c:330:12: error: 'unimac_mdio_resume' defined but not used [-Werror=unused-function] static int unimac_mdio_resume(struct device *d) drivers/net/phy/mdio-bcm-unimac.c:321:12: error: 'unimac_mdio_suspend' defined but not used [-Werror=unused-function] static int unimac_mdio_suspend(struct device *d) Marking the functions as __maybe_unused is the easiest workaround and avoids adding #ifdef checks.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
