From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>
When a kernel has CONFIG_PM=y and CONFIG_PM_SLEEP=n the following warnings are
seen:
drivers/input/touchscreen/mcs5000_ts.c:252:12: warning: 'mcs5000_ts_suspend' defined but not used [-Wunused-function]
static int mcs5000_ts_suspend(struct device *dev)
^
drivers/input/touchscreen/mcs5000_ts.c:262:12: warning: 'mcs5000_ts_resume' defined but not used [-Wunused-function]
static int mcs5000_ts_resume(struct device *dev)
Protect the suspend/resume functions with CONFIG_PM_SLEEP in order to fix these
build warnings.
