Because we probe the master ourselves (and fail if there is no master), it is not possible that we don't have a master device.
There is one catch though: device removal. We don't support that. It wasn't supported neither before this patch. Because the master device was only set in .pre_probe(), if a device was removed master_dev was a dangling pointer and transmitting a frame cause a panic. I don't see a good solution without having some sort of notify machanism when a udevice is removed.
