But what I see is the &dwc3_pci_dev_pm_ops is not NULL if CONFIG_PM_SLEEP
is not defined.
static foo(void)
{}
static goo(void)
{}
struct dev_pm_ops {
int a;
int b;
};
#define SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn)
#define SIMPLE_DEV_PM_OPS(name, suspend_fn, resume_fn) \
const struct dev_pm_ops name = { \
SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) \
}
SIMPLE_DEV_PM_OPS(test_name, foo, goo);
void main(void)
{
printf("the pointer of name is %p\n", &test_name);
return;
}
