Subject: stm class: Remove unnecessary pointer increment
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fb0801904bbbc7b109d4009520c7fa34bcfb7450;p=openwrt%2Fstaging%2Fblogic.git

stm class: Remove unnecessary pointer increment

Readability: a postfix increment is used on a pointer which is not
used anywhere afterwards, which may send the reader looking through
the function one extra time. Drop the unnecessary increment.
