No.
It is not.
On a recent kernel I managed to have this work (using
"CONFIG_MTD_PARTITIONED_MASTER=y").

Is it possible to retrieve (or re-create) the master device in an older
kernel (3.18)?
It does not have MTD_PARTITIONED_MASTER config option.
I know it won't be able to del/add partitions, but being able to write
to the whole,
unpartitioned device would be *very* useful nonetheless.

Thanks in advance
