Subject: x86/crash: Remove unnecessary comparison
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4599c6671b8119ed5455e4ed6b967b461c27a9f7;p=openwrt%2Fstaging%2Fblogic.git

x86/crash: Remove unnecessary comparison

The ret comparison and return are unnecessary as of commit f296f2634920
("x86/kexec: Remove walk_iomem_res() call with GART type")

elf_header_exclude_ranges() returns ret in any case, with or without this
comparison.
