The rework of the exynos DRM clock handling introduced
warnings for configurations that have CONFIG_PM disabled:
drivers/gpu/drm/exynos/exynos_hdmi.c:736:13: error: 'hdmi_clk_disable_gates' defined but not used [-Werror=unused-function]
static void hdmi_clk_disable_gates(struct hdmi_context *hdata)
^~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/exynos/exynos_hdmi.c:717:12: error: 'hdmi_clk_enable_gates' defined but not used [-Werror=unused-function]
static int hdmi_clk_enable_gates(struct hdmi_context *hdata)
The problem is that the PM functions themselves are inside of
an #ifdef, but some functions they call are not.
This patch removes the #ifdef and instead marks the PM functions
as __maybe_unused, which is a more reliable way to get it right.

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.
