Subject: [PATCH net-next 15/15] ice: fix clang warning regarding deadcode.DeadStores
Date: Mon,  7 Jun 2021 09:53:25 -0700	[thread overview]
Message-ID: <20210607165325.182087-16-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20210607165325.182087-1-anthony.l.nguyen@intel.com>

From: Paul M Stillwell Jr <paul.m.stillwell.jr@intel.com>

clang generates deadcode.DeadStores warnings when a variable
is used to read a value, but then that value isn't used later
in the code. Fix this warning.
