[PATCH v2 -next] platform: surface: fix non-PM_SLEEP build warnings

From: Randy Dunlap
Date: Mon Dec 14 2020 - 18:34:50 EST


Fix build warnings when CONFIG_PM_SLEEP is not enabled and these
functions are not used:

../drivers/platform/surface/surface_gpe.c:189:12: warning: ‘surface_gpe_resume’ defined but not used [-Wunused-function]
static int surface_gpe_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~
../drivers/platform/surface/surface_gpe.c:184:12: warning: ‘surface_gpe_suspend’ defined but not used [-Wunused-function]
static int surface_gpe_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~

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