Subject: [PATCH net-next] sun/niu: add __maybe_unused attribute to PM functions
Date:   Tue,  7 Jul 2020 13:11:22 +0530
Message-Id: <20200707074121.230686-1-vaibhavgupta40@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The upgraded .suspend() and .resume() throw
"defined but not used [-Wunused-function]" warning for certain
configurations.

Mark them with "__maybe_unused" attribute.

Compile-tested only.

Fixes: b0db0cc2f695 ("sun/niu: use generic power management")
