From 8e1974a2a02bf5b77831c686f01761163ea0cd3e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 29 Jan 2020 19:01:17 +0100 Subject: mptcp: Fix incorrect IPV6 dependency check If CONFIG_MPTCP=y, CONFIG_MPTCP_IPV6=n, and CONFIG_IPV6=m: net/mptcp/protocol.o: In function `__mptcp_tcp_fallback': protocol.c:(.text+0x786): undefined reference to `inet6_stream_ops' Fix this by checking for CONFIG_MPTCP_IPV6 instead of CONFIG_IPV6, like is done in all other places in the mptcp code.
