From 57b8045d13569b7d8a1861bd61b7b664e417f7bc Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 6 Apr 2015 12:00:39 +0200 Subject: [PATCH] mtd: Switch to PM ops Use dev_pm_ops instead of the legacy suspend/resume callbacks for the MTD class suspend and resume operations. While we are at it slightly reorder things to avoid the need for forward declarations.
