Subject: [PATCH] ethernet:netronome:nfp:move spin_lock_bh to spin_lock in tasklet
Date:   Fri,  7 Sep 2018 09:21:17 -0700
Message-Id: <20180907162117.47361-1-hangdianqj@163.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As you are already in a tasklet, it is unnecessary to call spin_lock_bh.
