drm/exynos: constify exynos_drm_crtc_ops structures
Declare exynos_drm_crtc_ops structures as const as they are only passed as an argument to the function exynos_drm_crtc_create. This argument is of type const struct exynos_drm_crtc_ops *, so exynos_drm_crtc_ops structures having this property can be declared const. Done using Coccinelle: @r disable optional_qualifier@ identifier i; position p; @@ static struct exynos_drm_crtc_ops i@p={...}; @ok@ position p; identifier r.i; @@ exynos_drm_crtc_create(...,&i@p,...) @bad@ position p!={r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ +const struct exynos_drm_crtc_ops i; File size before: text data bss dec hex filename 5008 280 0 5288 14a8 exynos/exynos5433_drm_decon.o File size after: text data bss dec hex filename 5120 176 0 5296 14b0 exynos/exynos5433_drm_decon.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1483984493-25284-1-git-send-email-bhumirks@gmail.com
