+Subject: [PATCH] drm: Use the state pointer directly in atomic_check
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Now that atomic_check takes the global atomic state as a parameter, we
+don't need to go through the pointer in the CRTC state.
+
+This was done using the following coccinelle script:
+
+@ crtc_atomic_func @
+identifier helpers;
+identifier func;
+@@
+
+static struct drm_crtc_helper_funcs helpers = {
+	...,
+	.atomic_check = func,
+	...,
+};
+
+@@
+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);
+  ... when != crtc_state
+- crtc_state->state
++ state
+  ...
+ }
+
+@@
+struct drm_crtc_state *crtc_state;
+identifier crtc_atomic_func.func;
+identifier crtc, state;
