From 841670351e8e5acbe9f7367f7df661a5d0cfef79 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Fri, 12 Apr 2013 09:41:44 +0000 Subject: PM / Runtime: Improve prepare handling at system suspend for genpd When genpd prepares for a system suspend it will fetch a runtime reference for the device. When returning it we now use the asyncronous runtime PM API. Thus we don't have to wait for the device to become idle|suspended before we move on and handle the next device in queue.
