Subject: [PATCH 22/28] drivers: tty: Call cpu_latency_qos_*() instead of pm_qos_*()
Date: Wed, 12 Feb 2020 00:27:04 +0100 [thread overview]
Message-ID: <2339403.frKpfgBVMR@kreacher> (raw)
In-Reply-To: <1654227.8mz0SueHsU@kreacher>
From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
Call cpu_latency_qos_add/update/remove_request() instead of
pm_qos_add/update/remove_request(), respectively, because the
latter are going to be dropped.
No intentional functional impact.
