From b7808056141bc4d67213036921a5a685ebec0274 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 22 Apr 2011 22:02:55 +0200 Subject: ARM / Integrator: Use struct syscore_ops for core PM Replace the sysdev class and struct sys_device used for power management by the Integrator interrupt-handling code with a struct syscore_ops object which is simpler.
