driver core: Make parameter check consistent for API cluster device_(…
…for_each|find)_child() The following API cluster takes the same type parameter list, but do not have consistent parameter check as shown below. device_for_each_child(struct device *parent, ...) // check (!parent->p) device_for_each_child_reverse(struct device *parent, ...) // same as above device_find_child(struct device *parent, ...) // check (!parent) Fixed by using consistent check (!parent || !parent->p) which covers both existing checks for the cluster.
