Subject: mm: hugetlb: remove redundant `if' operation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=91f47662dfaa5b459aebe13284c6c38db27350dc;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mm: hugetlb: remove redundant `if' operation

At this point we already know that 'addr' is not NULL so get rid of
redundant 'if'.  Probably gcc eliminate it by optimization pass.
