That is the original code, I just moved it in a different function.
Its probably best if we use a separate patch for this, but is it worth
it?

per bus_find_device() :

 * The callback should return 0 if the device doesn't match and
non-zero
 * if it does.  If the callback returns non-zero, this function will
 * return to the caller and not iterate over any more devices.
 */
struct device *bus_find_device(struct bus_type *bus,
                               struct device *start, void *data,
                               int (*match)(struct device *dev, void *data))
