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)

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.

The conversion was done using the coccinelle script below plus some
manual changes for vmwgfx, built tested on all the drivers.

Now that atomic_check takes the global atomic state as a parameter, we
don't need to go through the pointer in the plane state.

This was done using the following coccinelle script:

Some drivers are storing the plane->state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.

In order to ease subsequent reworks and to avoid confusing or
inconsistent names, let's rename those variables to new_state.

This was done using the following coccinelle script, plus some manual
changes for mtk and tegra.

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

The conversion was done using the coccinelle script below, built tested on
all the drivers.

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:

 	.atomic_disable = func,

 	.atomic_update = func,

)

Hi Thomas,

Thanks for your review!

So, the function already had a variable named old_state, so I was
actually trying to make the drivers consistent here: having one variable
with old_state and new_plane_state felt weird.

The heuristic is thus to use the convention of the driver if one exists
already, and if there's none pick new_plane_state.

It makes it indeed inconsistent across drivers, but it felt more natural
to be consistent within a single driver.

Maxime
