on an unrelated note, this NULL check is unnecessary.  the core func
already takes care of checking the pointer.

drivers/base/dd.c:
408 void *dev_get_drvdata(const struct device *dev)
409 {
410         if (dev && dev->p)
411                 return dev->p->driver_data;
412         return NULL;
413 }
