Right now there is a message for _every_ mtd device that gets created
only if mtdblock support is built-in. Of course enabling mtdblock if
you don't use it is a waste of space, but it is far less an issue than
people actually using it and I think that is our main target.

The warnings from Ezequiel were a good idea but right now I think we
all agree that they are too frequent. A single warning would be an
improvement, but otherwise a warning only when ->open() gets called
seems a good enough step forward for me.

Thanks,
