[PATCH v2 0/5] fbcon: Move bitops callbacks into separate struct

[Thomas Zimmermann <tzimmermann@suse.de>]

Instances of fbcon use a number callbacks to support tile-based
drawing or console rotation. 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.

v2:
- rename struct fbcon_ops to struct fbcon_par
- drop patch 6

Thomas Zimmermann (5):
  fbcon: Fix empty lines in fbcon.h
  fbcon: Rename struct fbcon_ops to struct fbcon_par
  fbcon: Set rotate_font callback with related callbacks
  fbcon: Move fbcon callbacks into struct fbcon_bitops
  fbcon: Streamline setting rotated/unrotated bitops
