From 1a941929a4163a147764711f6bfe2ad9f3614abb Mon Sep 17 00:00:00 2001

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;
@@
func(struct drm_crtc *crtc, struct drm_atomic_state *state) {
...
- crtc_state->state
+ state
...
}
