Analyze and fix the following issue in the Linux kernel code: ipv6: Fix bug in ipv6_chk_same_addr().
Problem Details: hlist_for_each_entry(p...) will not necessarily initialize 'p' to anything if the hlist is empty. GCC notices this and emits a warning. Just return true explicitly when we hit a match, and return false is we fall out of the loop without one. Signed-off-by: David S. Miller <davem@davemloft.net>
