Patch series "Some minor cleanup patches resent". The first three patches trivial clean up patches. And for the patch "kexec: replace crash_mem_range with range", I got a ibm-p9wr ppc64le system to test, it works well. This patch (of 4): elfcorehdr_alloc() allocates a memory chunk for elfcorehdr_addr with kzalloc(). If is_vmcore_usable() returns false, elfcorehdr_addr is a predefined value. If parse_crash_elf_headers() gets some error and returns a negetive value, the elfcorehdr_addr should be released with elfcorehdr_free(). Fix it by calling elfcorehdr_free() when parse_crash_elf_headers() fails.

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.
