Subject: [PATCH v5 10/13] drm/fb-helper: Export helpers for marking damage areas
Date: Tue, 30 May 2023 17:12:25 +0200	[thread overview]
Message-ID: <20230530151228.22979-11-tzimmermann@suse.de> (raw)
In-Reply-To: <20230530151228.22979-1-tzimmermann@suse.de>

Export drm_fb_helper_damage() and drm_fb_helper_damage_range(), which
handle damage areas for fbdev emulation. This is a temporary export
that allows to move the DRM I/O helpers for fbdev into drivers. Only
fbdev-generic and i915 need them. Both will be updated to implement
damage handling by themselves and the exported functions will be removed.

v4:
	* update interfaces
