[ Upstream commit adfaec30ffaceecd565e06adae367aa944acc3c9 ] We anyway don't use any return values from fadump_cma_init(). Since fadump_reserve_mem() from where fadump_cma_init() gets called today, already has the required checks. This patch makes this function return type as void. Let's also handle extra cases like return if fadump_supported is false or dump_active, so that in later patches we can call fadump_cma_init() separately from setup_arch().

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.
