Subject[PATCH] platform/surface: mark PM functions as __maybe_unused
From: Arnd Bergmann <>

When CONFIG_PM is disabled, the compiler produces harmless warnings:

drivers/platform/surface/surface_gpe.c:184:12: error: unused function 'surface_gpe_suspend' [-Werror,-Wunused-function]
static int surface_gpe_suspend(struct device *dev)
drivers/platform/surface/surface_gpe.c:189:12: error: unused function 'surface_gpe_resume' [-Werror,-Wunused-function]
static int surface_gpe_resume(struct device *dev)

Mark these as __maybe_unused to shut up the warning.

Fixes: 274335f1c557 ("platform/surface: Add Driver to set up lid GPEs on MS Surface device")
