Well, the other APIs currently return an int:
extern int of_device_is_compatible(const struct device_node *device,
const char *);
extern int of_device_is_available(const struct device_node *device);
[...]
extern int of_machine_is_compatible(const char *compat);
Do you think it is best to change all of them at once, or just the
newly introduced function?
