Subject: [PATCH 1/3] drm/exynos: Suspend/resume is unused if !PM
Date: Thu, 24 Sep 2015 12:14:13 +0200 [thread overview]
Message-ID: <1443089655-15352-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
Protect the suspend and resume callbacks with an #ifdef CONFIG_PM_SLEEP
guard to avoid "defined but not used" warnings.
