Subject: chcr: ensure cntrl is initialized to fix bit-wise or'ing of garabage
data
Patch-mainline: v4.16-rc1
Git-commit: df807a19957c2917fd5a4f5812e240a250066742
References: bsc#1104270 FATE#325931
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")
