Subject: [PATCH AUTOSEL 4.18 35/56] ice: Fix potential return of uninitialized value
Date: Thu, 20 Sep 2018 02:47:52 +0000 [thread overview]
Message-ID: <20180920024716.58490-35-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180920024716.58490-1-alexander.levin@microsoft.com>
From: Jesse Brandeburg <jesse.brandeburg@intel.com>
[ Upstream commit dab0588fb616c1774bbf108eab1749dda4ac6942 ]
In ice_vsi_setup_[tx|rx]_rings, err is uninitialized which can result in
a garbage value return to the caller. Fix that.
