Clean this up to just initialize buf to buf_start + offsets[i] to clean up the clang build warning: "Value stored to 'buf' during its initialization is never read" Signed-off-by: Colin Ian King Signed-off-by: Pablo Neira Ayuso --- diff --git a/net/bridge/netfilter/ebtables.c b/net/bridge/netfilter/ebtables.c index 83951f978445..54c274dbf4f1 100644 --- a/net/bridge/netfilter/ebtables.c +++ b/net/bridge/netfilter/ebtables.c @@ -2111,9 +2111,8 @@ static int size_entry_mwt(struct ebt_entry *entry, const unsigned char *base, for (i = 0, j = 1 ; j < 4 ; j++, i++) { struct compat_ebt_entry_mwt *match32; unsigned int size; - char *buf = buf_start; + char *buf = buf_start + offsets[i]; - buf = buf_start + offsets[i]; if (offsets[i] > offsets[j]) return -EINVAL;
