Subject: net: don't warn in inet diag when IPV6 is disabled
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1e64d7cbfdce4887008314d5b367209582223f27;p=openwrt%2Fstaging%2Fblogic.git

net: don't warn in inet diag when IPV6 is disabled

If IPV6 was disabled, then ss command would cause a kernel warning
because the command was attempting to dump IPV6 socket information.
The fix is to just remove the warning.
