[PATCH v2 00/19] backlight: Constify lcd_ops

[Krzysztof Kozlowski]

Hi,

Changes in v2:
- Collect tags, including wrongly places Thomas' tag (which requires me
  to manually edit 15 other patches to drop it).
- Combine here checkpatch patch:
  https://lore.kernel.org/all/20240414185440.288812-1-krzk@kernel.org/
- Link to v1: https://lore.kernel.org/r/20240414-video-backlight-lcd-ops-v1-0-9b37fcbf546a@kernel.org

Dependencies
============
All further patches depend on the first patch.  Therefore everything
could go via backlight tree (please ack) or via cross-tree pulls. Or
whatever maintainer choose, just coordinate this with backlight.

Best regards,
Krzysztof

[PATCH v2 01/19] backlight: Constify lcd_ops

[Krzysztof Kozlowski]

'struct lcd_ops' passed in lcd_device_register() is not modified by core
backlight code, so it can be made const for code safety.  This allows
drivers to also define the structure as const.
