From 7650572a8baa79d317ca5d37a7998593ff0767af Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 6 Jul 2012 19:08:53 +0200 Subject: [PATCH] omap-rng: Use struct dev_pm_ops for power management Make the omap-rng driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver.
