Subject: arm64/mm: Drop redundant addr increment in set_huge_pte_at()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aa46e18836c07e4d81491d47f8deeba840e780f0;p=thirdparty%2Fkernel%2Fstable.git

arm64/mm: Drop redundant addr increment in set_huge_pte_at()

The 'addr' need not be incremented in the loop because that is not going to
be used subsequently.
