drm: Use state helper instead of the plane state pointer
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);
...
