    drm: exynos: mark pm functions as __maybe_unused · 7e175100
    Arnd Bergmann authored
    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.
