Subject: [PATCH nf-next 02/18] netfilter: conntrack: use correct format characters

From: Bill Wendling <>

When compiling with -Wformat, clang emits the following warnings:

net/netfilter/nf_conntrack_helper.c:168:18: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]

Use a string literal for the format string.
