The fields are writeable in struct fbcon_ops. Each case; unrotated, various rotated and tile-based drawing; uses a set of related calbacks. Updating these 'bitops' at runtime is spread throughout various helper functions. This series puts related callbacks into dedicated instances of the new type struct fbcon_bitops. Changing the callbacks at runtime then only requires to pick the correct instance. It further allows the various struct fbcon_bitops' to be declared 'static const', which makes them write-protected at runtime. Makes the fbcon bitops easier and safer to use and modify.
