From 0b07ee944701dabcddc294d903b5e8e21c2c5d95 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 4 Jul 2019 13:06:17 +0530 Subject: PM / QOS: Pass request type to dev_pm_qos_{add|remove}_notifier() In order to use the same set of routines to register notifiers for different request types, update the existing dev_pm_qos_{add|remove}_notifier() routines with an additional parameter: request-type. For now, it only supports resume-latency request type but will be extended to frequency limit (min/max) constraints later on.
