Right, I removed all your other mentions to the same issue but I'll double
check all the drivers to be sure that use const.

In an early version of the series I just passed NULL for all drivers but
Mark said that is more future proof to pass the descriptor and I agree.

I guess I should just remove the warning and only show an error if the
descriptor is not NULL and also the map mode function is defined but
the callback returns an error.
