Subject: [PATCH 5/6] Input: evdev - Enable runtime PM of the evdev input handler
Date: Tue, 31 Mar 2015 18:14:49 +0200	[thread overview]
Message-ID: <1427818501-10201-6-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1427818501-10201-1-git-send-email-tomeu.vizoso@collabora.com>

So ancestor devices can remain runtime-suspended when the system goes
into a sleep state, they and all of their descendant devices need to
have runtime PM enabled.
