Subject: [PATCH] wireguard: selftests: initalize ipv6 members to NULL to
|
||
|
|
squelch clang warning
|
||
|
|
|
||
|
|
commit 4fed818ef54b08d4b29200e416cce65546ad5312 upstream.
|
||
|
|
|
||
|
|
Without setting these to NULL, clang complains in certain
|
||
|
|
configurations that have CONFIG_IPV6=n:
|
||
|
|
|
||
|
|
In file included from drivers/net/wireguard/ratelimiter.c:223:
|
||
|
|
drivers/net/wireguard/selftest/ratelimiter.c:173:34: error: variable 'skb6' is uninitialized when used here [-Werror,-Wuninitialized]
|
||

ret = timings_test(skb4, hdr4, skb6, hdr6, &test_count);

struct ipv6hdr *hdr6;

|
|
^
|

|

We silence this warning by setting the variables to NULL as the warning
|
||
|
|
suggests.
