Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.
