When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.

Therefore, remove the error printing here to simplify code and reduce the
binary size.

msm-next pull request has a baseline with stuff from -fixes, roll
forward first.

Some simple conflicts in amdgpu, ttm and one in i915 where git gets
confused and tries to add the same function twice.

Many drivers reference the plane-&gt;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,

 	.atomic_update = func,

<title>drm/atomic: Pass the full state to planes atomic disable and update</title>

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.

Some drivers are storing the plane-&gt;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.
