From 2b1d88cda32f81685bae45c00bf517f77bcda3cd Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 15 Oct 2015 17:02:19 +0200 Subject: PM / Domains: Merge measurements for PM QoS device latencies Measure latency does by itself contribute to an increased latency, thus we should avoid it when it isn't needed. By merging the latency measurements for the ->save_state() and the ->stop() callbacks, we get one measurement instead of two and we get one value to store instead of two. Let's also apply the likewise change for the ->start() and ->restore_state() callbacks. Signed-off-by: Ulf Hansson Reviewed-by: Lina Iyer Acked-by: Kevin Hilman Signed-off-by: Rafael J.
