Commit Message

Arnd Bergmann Aug. 14, 2018, 9:07 a.m. UTC 
When CONFIG_RDS_TCP is built-in and CONFIG_IPV6 is a loadable
module, we get a link error agains the modular ipv6_chk_addr()
function:

net/rds/tcp.o: In function `rds_tcp_laddr_check':
tcp.c:(.text+0x3b2): undefined reference to `ipv6_chk_addr'

This adds back a dependency that forces RDS_TCP to also be
a loadable module when IPV6 is one.

Fixes: e65d4d96334e ("rds: Remove IPv6 dependency")
