of: dynamic: Synchronize of_changeset_destroy() with the devlink removals

commit 8917e7385346bd6584890ed362985c219fe6ae84 upstream.

In the following sequence:
1) of_platform_depopulate()
2) of_overlay_remove()

During the step 1, devices are destroyed and devlinks are removed.
During the step 2, OF nodes are destroyed but
__of_changeset_entry_destroy() can raise warnings related to missing
of_node_put():
ERROR: memory leak, expected refcount 1 instead of 2 ...

Indeed, during the devlink removals performed at step 1, the removal
itself releasing the device (and the attached of_node) is done by a job
queued in a workqueue and so, it is done asynchronously with respect to
function calls.
When the warning is present, of_node_put() will be called but wrongly
too late from the workqueue job.

In order to be sure that any ongoing devlink removals are done before
the of_node destruction, synchronize the of_changeset_destroy() with the
devlink removals.

of: dynamic: Fix potential memory leak in of_changeset_action()

Smatch complains that the error path where "action" is invalid leaks
the "ce" allocation:
drivers/of/dynamic.c:935 of_changeset_action()
warn: possible memory leak of 'ce'

Fix this by doing the validation before the allocation.

Note that there is not any actual problem with upstream kernels. All
callers of of_changeset_action() are static inlines with fixed action
values.

Pull devicetree updates from Rob Herring:
"DT core:

- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.

- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.

- Refactor node and property manipulation functions to better share
code with old API and changeset API

- Refactor changeset print functions to a common implementation

- Move some platform_device specific functions into of_platform.c

Bindings:

- Treewide fixing of typos

- Treewide clean-up of SPDX tags to use 'OR' consistently

- Last chunk of dropping unnecessary quotes. With that, the check for
unnecessary quotes is enabled in yamllint.

- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format

- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450

controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

of: dynamic: Move dead property list check into property add/update functions

The changeset code checks for a property in the deadprops list when
adding/updating a property, but of_add_property() and
of_update_property() do not. As the users of these functions are pretty
simple, they have not hit this scenario or else the property lists
would get corrupted.

With this there are 3 cases of removing a property from either deadprops
or properties lists, so add a helper to find and remove a matching
property.

of: dynamic: Fix race in getting old property when updating property

__of_update_property() returns the existing property if there is one, but
that value is never added to the changeset. Updates work because the
existing property was also retrieved before in of_changeset_action(),
but that is racy as of_changeset_action() doesn't hold any locks. The
property could be changed before the changeset is applied.

of: dynamic: Refactor changeset action printing to common helpers

Several places print the changeset action with node and property
details. Refactor these into a common printing helper. The complicating
factor is some prints are debug and some are errors. Solve this with a
bit of preprocessor magic.

Some cases printed the 'cset' which was the changeset entry pointer
rather than the whole changeset itself. The changeset entry is not all that
interesting and gets obfuscated by default anyways. So just drop it.

Fix this by moving the printing in __of_changeset_entry_apply() outside

name, use the existing "action_names" to refactor the prints into a
single print.
