Subject: [PATCH] ARM: common: edma: edma_pm_resume may be unused
Message-ID: <4363971.teBOlf16kG@wuerfel>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

The recently introduced resume hook in the edma driver
is not referenced when CONFIG_PM_SLEEP is not set, which
results in a compile warning in keystone_defconfig builds.

This adds an appropriate #ifdef.

I'm applying this as the obvious fixup on top of the next/drivers
branch.
