From 37418bf14c1392260d633e3b4448b78c2f15044a Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 19 Feb 2021 13:00:30 +0100 Subject: drm: Use state helper instead of the plane state pointer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_update or atomic_disable hooks, which would be the new plane state in the global atomic state since _swap_state happened when those hooks are run. Use the drm_atomic_get_new_plane_state helper to get that state to make it more obvious. This was made using the coccinelle script below: @ plane_atomic_func @ identifier helpers; identifier func; @@ ( static const struct drm_plane_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; | static const struct drm_plane_helper_funcs helpers = { ..., .atomic_update = func, ..., }; ) @ adds_new_state @ identifier plane_atomic_func.func; identifier plane, state; identifier new_state; @@ func(struct drm_plane *plane, struct drm_atomic_state *state) { ... - struct drm_plane_state *new_state = plane->state; + struct drm_plane_state *new_state = drm_atomic_get_new_plane_state(state, plane); ... } @ include depends on adds_new_state @ @@ #include @ no_include depends on !include && adds_new_state @ @@ + #include #include Reviewed-by: Ville Syrjälä Signed-off-by: Maxime Ripard Acked-by: Thomas Zimmermann Link: https://lore.kernel.org/r/20210219120032.260676-1-maxime@cerno.tech --- drivers/gpu/drm/meson/meson_overlay.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/drm/meson/meson_overlay.c') diff --git a/drivers/gpu/drm/meson/meson_overlay.c b/drivers/gpu/drm/meson/meson_overlay.c index de2e95ad2de5..ed063152aecd 100644 --- a/drivers/gpu/drm/meson/meson_overlay.c +++ b/drivers/gpu/drm/meson/meson_overlay.c @@ -471,7 +471,8 @@ static void meson_overlay_atomic_update(struct drm_plane *plane, struct drm_atomic_state *state) { struct meson_overlay *meson_overlay = to_meson_overlay(plane); - struct drm_plane_state *new_state = plane->state; + struct drm_plane_state *new_state = drm_atomic_get_new_plane_state(state, + plane); struct drm_framebuffer *fb = new_state->fb; struct meson_drm *priv = meson_overlay->priv; struct drm_gem_cma_object *gem; -- cgit v1.2.3
