Subject: [PATCH] staging: r8188eu: refactor recvframe_defrag()
Date:   Wed, 20 Mar 2019 17:31:44 +0300
Message-Id: <20190320143144.17663-1-insafonov@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Local variables pfhdr and prframe always have a same value,
so one of them is unnecessary.
