Subject: [PATCH] memory: tegra: avoid unused function warnings
Date:   Wed,  8 Apr 2020 21:00:30 +0200
Message-Id: <20200408190043.532711-1-arnd@arndb.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The suspend/resume functions have no callers depending on
configuration, so they must be marked __maybe_unused to
avoid these harmless warnings:

drivers/memory/tegra/tegra186.c:1578:12: error: 'tegra186_mc_resume' defined but not used [-Werror=unused-function]
 1578 | static int tegra186_mc_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~
drivers/memory/tegra/tegra186.c:1573:12: error: 'tegra186_mc_suspend' defined but not used [-Werror=unused-function]
 1573 | static int tegra186_mc_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~

Fixes: 177602b00641 ("memory: tegra: Add system sleep support")
