From 5f986c590fcf4284924fcda991cf14ab32bff49f Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 23 Oct 2012 01:07:27 +0200 Subject: PM / QoS: Prepare device structure for adding more constraint types Currently struct dev_pm_info contains only one PM QoS constraints pointer reserved for latency requirements. Since one more device constraints type (i.e. flags) will be necessary, introduce a new structure, struct dev_pm_qos, that eventually will contain all of the available device PM QoS constraints and replace the "constraints" pointer in struct dev_pm_info with a pointer to the new structure called "qos".
