In case cma_init_reserved_mem failed, need to free the memblock allocated by memblock_reserve or memblock_alloc_range. Quote Catalin's comments: https://lkml.org/lkml/2019/2/26/482 Kmemleak is supposed to work with the memblock_{alloc,free} pair and it ignores the memblock_reserve() as a memblock_alloc() implementation detail. It is, however, tolerant to memblock_free() being called on a sub-range or just a different range from a previous memblock_alloc(). So the original patch looks fine to me.

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.
