Subject: sg_init_table() should use unsigned loop index variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=513f54b78f9594927ede66b6c66a70c1bae0c4ca;p=openwrt%2Fstaging%2Fblogic.git

sg_init_table() should use unsigned loop index variable

Clean up: fix a mixed sign comparison in sg_init_table() accidentally
introduced by commit d6ec0842.  The sign of the loop index variable
should match the sign of the "nents" argument.
