chcr: ensure cntrl is initialized to fix bit-wise or'ing of garabage data
In the case where skb->ip_summed != CHECKSUM_PARTIAL then cntrl contains garbage value and this is possibly being bit-wise or'd and stored into cpl->ctrl1. Fix this by initializing cntrl to zero. Cleans up clang warning: drivers/crypto/chelsio/chcr_ipsec.c:374:9: warning: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage Fixes: 6dad4e8ab3ec ("chcr: Add support for Inline IPSec") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
