Subject: sg_last() should use unsigned loop index variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=74eb94f7b84f4e631a0e020991fb16f17ce85ab7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sg_last() should use unsigned loop index variable

Clean up: fix a mixed sign comparison in sg_last() accidentally
introduced by commit 70eb8040.  The sign of the loop index variable
should match the sign of the "nents" argument.
