[PATCH 6.16 349/457] drm/tests: Do not use drm_fb_blit() in format-helper tests

6.16-stable review patch. If anyone has any objections, please let me know.

------------------

From: Thomas Zimmermann tzimmermann@suse.de

[ Upstream commit 5a4856e0e38109ba994f369962f054ecb445c098 ]

Export additional helpers from the format-helper library and open-code drm_fb_blit() in tests. Prepares for the removal of drm_fb_blit(). Only sysfb drivers use drm_fb_blit(). The function will soon be removed from format helpers and be refactored within sysfb helpers.
