Hi Maxime, Thank you for the patch. On Fri, Jan 15, 2021 at 01:56:54PM +0100, Maxime Ripard wrote:
Most drivers call the argument to the plane atomic_check hook simply
state, which is going to conflict with the global atomic state in a
later rework. Let's rename it to new_plane_state (or new_state depending
on the convention used in the driver).
This was done using the coccinelle script below, and built tested:
@ plane_atomic_func @
identifier helpers;
identifier func;
@@
static const struct drm_plane_helper_funcs helpers = {
.atomic_check = func,
};
@ has_old_state @
identifier plane_atomic_func.func;
identifier plane;
expression e;
symbol old_state;
symbol state;

func(struct drm_plane *plane, struct drm_plane_state *state)
