Zijun Hu f1142d4e7a of: reserved-memory: Do not make kmemleak ignore freed address
[ Upstream commit 29091a5256 ]

early_init_dt_alloc_reserved_memory_arch() will free address @base when
suffers memblock_mark_nomap() error, but it still makes kmemleak ignore
the freed address @base via kmemleak_ignore_phys().

That is unnecessary, besides, also causes unnecessary warning messages:

kmemleak_ignore_phys()
 -> make_black_object()
    -> paint_ptr()
       -> kmemleak_warn() // warning message here.

Fix by avoiding kmemleak_ignore_phys() when suffer the error.

Fixes: 658aafc813 ("memblock: exclude MEMBLOCK_NOMAP regions from kmemleak")

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.
