From c3146df2b735912eddd1d7c080c9377d5df0ae94 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 12 Mar 2011 22:16:51 +0100 Subject: ACPI: Use syscore_ops instead of sysdev class and sysdev ACPI uses a sysdev class and a sysdev for executing irqrouter_resume() before turning on interrupts on the boot CPU. However, since irqrouter_resume() ignores its argument, the entire mechanism may be replaced with a struct syscore_ops object which is considerably simpler. Signed-off-by: Rafael J.
