Thanks Dmitry, not sure why this hasn't been merged yet.

Taking a further look at this I noticed that we never pushed the
firmware to linux-firmware either, which I think was because we where
uncertain of the directory structure at the time - a discussion which
has been settled since.

But if we're pushing things to linux-firmware, does anyone object
against following the existing style and squashing the mdt+bNN files
into .mbn (and thereby making this modem.mbn and below wcnss.mbn)?
