This is the correct fix.  Remove the DEVICE line.

The default DEVICE line (which is in effect if no DEVICE line is explicitly
given) is

   DEVICE partitions containers

which essentially means "feel free to use use anything in an md array".

A DEVICE line is only needed if you want to explicitly list some smaller
subset of things.

There was a time when a DEVICE line was needed, but that is long gone now.
