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.
Fixes: 914d9d831e61 ("of: dynamic: Refactor action prints to not use "%pOF" inside devtree_lock")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
