drm/format-helper: Export drm_fb_clip_offset()
Provide a function that computes the offset into a blit destination buffer. This will allow to move destination-buffer clipping into the format-helper callers. v4: * add missing '@' for parameter documentation * fix typo 'frambuffer' v2: * provide documentation (Sam) * return 'unsigned int' (Sam, Noralf) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20211110103702.374-2-tzimmermann@suse.de
