Subject: [PATCH] octeontx2-af: fix uninitialized variable
Date: Mon, 20 Sep 2021 09:53:47 -0700 [thread overview]
Message-ID: <20210920165347.164087-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
Building with clang 13 reports this error
rvu_nix.c:4600:7: error: variable 'val' is used uninitialized whenever
'if' condition is false
if (!is_rvu_otx2(rvu))
^~~~~~~~~~~~~~~~~
So initialize val.
Fixes: 4b5a3ab17c6c ("octeontx2-af: Hardware configuration for inline IPsec")
