From e7176a37d436a214f6a7727ea7986c654cbee8f0 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 15 Mar 2010 21:43:11 +0100 Subject: power: support _noirq actions on device types and classes The new-style dev_pm_ops provide callbacks for both IRQs enabled and disabled. However, the _noirq variants were only called for buses registered with a device, not for classes and types. In order to properly use dev_pm_ops in class pcmcia_socket_class, support _noirq actions also on classes and types. Signed-off-by: Dominik Brodowski Acked-by: Rafael J.
