Subject: [TCP]: Fix botched memory leak fix to tcpprobe_read().
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=18b6fe64d4d1f6e0a2c71429a5e5074f43e29203;p=openwrt%2Fstaging%2Fblogic.git

[TCP]: Fix botched memory leak fix to tcpprobe_read().

Somehow I clobbered James's original fix and only my
subsequent compiler warning change went in for that
changeset.

Get the real fix in there.

Noticed by Jesper Juhl.
