Subject: [PATCH 7/8] staging: mt7621-pci: remove some dead code.
Cc:     devel@driverdev.osuosl.org, linux-kernel@vger.kernel.org
Message-ID: <152540991631.12190.9879547396075931701.stgit@noble>
In-Reply-To: <152540982998.12190.15220622955317261586.stgit@noble>
References: <152540982998.12190.15220622955317261586.stgit@noble>
User-Agent: StGit/0.17.1-dirty
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 7bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some code is dead because it is commented out.
Some is dead because it is uninteresting printks.
Some is dead because it declares unused functions.

Remove it all.
