From 96d9d0b5dc17e80cefbd7c5be15a5072d33513f8 Mon Sep 17 00:00:00 2001 From: Sahara Date: Fri, 21 Jun 2013 11:12:30 +0900 Subject: PM / QoS: Add dev_pm_qos_request tracepoints Adds tracepoints to dev_pm_qos_add_request, dev_pm_qos_update_request, and dev_pm_qos_remove_request. It's useful for checking device name, dev_pm_qos_request_type, and value. Signed-off-by: Sahara Signed-off-by: Rafael J.
