drm: Use state helper instead of CRTC state pointer
Many drivers reference the crtc->pointer in order to get the current CRTC state in their atomic_begin or atomic_flush hooks, which would be the new CRTC state in the global atomic state since _swap_state happened when those hooks are run. Use the drm_atomic_get_new_crtc_state helper to get that state to make it more obvious. This was made using the coccinelle script below: @ crtc_atomic_func @ identifier helpers; identifier func; @@ ( static struct drm_crtc_helper_funcs helpers = { ..., .atomic_begin = func, ..., }; | static struct drm_crtc_helper_funcs helpers = { ..., .atomic_flush = func, ..., }; ) @@ identifier crtc_atomic_func.func; identifier crtc, state; symbol crtc_state; expression e; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct tegra_dc_state *crtc_state = e; + struct tegra_dc_state *dc_state = e; <+... - crtc_state + dc_state ...+> } @@ identifier crtc_atomic_func.func; identifier crtc, state; symbol crtc_state; expression e; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct mtk_crtc_state *crtc_state = e; + struct mtk_crtc_state *mtk_crtc_state = e; <+... - crtc_state + mtk_crtc_state ...+> } @ replaces_new_state @ identifier crtc_atomic_func.func; identifier crtc, state, crtc_state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct drm_crtc_state *crtc_state = crtc->state; + struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... } @@ identifier crtc_atomic_func.func; identifier crtc, state, crtc_state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... - crtc->state + crtc_state ... } @ adds_new_state @ identifier crtc_atomic_func.func; identifier crtc, state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { + struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... - crtc->state + crtc_state ... } @ include depends on adds_new_state || replaces_new_state @ @@ #include <drm/drm_atomic.h> @ no_include depends on !include && (adds_new_state || replaces_new_state) @ @@ + #include <drm/drm_atomic.h> #include <drm/...> Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: "James (Qian) Wang" <james.qian.wang@arm.com> Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Mihail Atanassov <mihail.atanassov@arm.com> Cc: Brian Starkey <brian.starkey@arm.com> Cc: Russell King <linux@armlinux.org.uk> Cc: Paul Cercueil <paul@crapouillou.net> Cc: Chun-Kuang Hu <chunkuang.hu@kernel.org> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Sandy Huang <hjc@rock-chips.com> Cc: "Heiko Stübner" <heiko@sntech.de> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201105164518.392891-1-maxime@cerno.tech
