I think these cases can still be covered - mtd_device_register() can be 
called twice - once with partitions and once without so it's just like 
calling add_mtd_device() then add_mtd_partitions().  The unregistering 
code deletes all registered partitions then only the master if it has 
been registered.

I don't believe these patches should have changed the behaviour of any 
of the drivers (other than it's now not possible to select whether the 
device is partitioned or not by a Kconfig option), but that can be done 
at runtime through command line partitioning perhaps.
