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.
