Subject: [NETFILTER]: nf_conntrack: sparse warnings
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=96eb24d770381b8a257b26183f6b6c131ad51ab9;p=openwrt%2Fstaging%2Fblogic.git

[NETFILTER]: nf_conntrack: sparse warnings

The hashtable size is really unsigned so sparse complains when you pass
a signed integer.  Change all uses to make it consistent.
