media-ctl propagates the output pad format to all remote subdevices'

Ah cool, I wasn't aware media-ctl did this, but it makes sense and
makes it easier on the user.
To be precise, userspace is responsible for propagating formats *between*
subdevs (source to sink, over a link) and drivers for propagating formats *in*
subdevs (sink to source, inside the subdev).
Hi Laurent, yes thanks for that clarification.
Steve
