Why not removing the ->priv field from the bcma_sflash struct
definition in this patch?
If it needs to go through a different tree we can ack the patch and let
the other maintainer(s) take the whole series.

Note that ->mtd seems to be unused, and should probably be removed as
well (in a separate patch of course). But I guess you already know that.
