Replace gma500's internal framebuffer creation with DRM's standard helper drm_gem_fb_create(). The result is equivalent. Only keep the existing tests for color depth and pitch alignment. v2: - rebase on upstream changes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patch.msgid.link/20260206133458.226467-6-tzimmermann@suse.de
