[PATCH 1/5] drm/fb-helper: Set damage-clip area in helper

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Set the damage area in the new helper drm_fb_helper_add_damage_clip().
It can now be updated without scheduling the damage worker. This change
will help to remove the damage worker entirely. No functional changes.
