Subject: [driver-core PATCH v4 6/6] PM core: Use new async_schedule_dev command
Date: Mon, 15 Oct 2018 08:09:38 -0700	[thread overview]
Message-ID: <20181015150938.29520.30034.stgit@localhost.localdomain> (raw)
In-Reply-To: <20181015150305.29520.86363.stgit@localhost.localdomain>

This change makes it so that we use the device specific version of the
async_schedule commands to defer various tasks related to power management.
By doing this we should see a slight improvement in performance as any
device that is sensitive to latency/locality in the setup will now be
initializing on the node closest to the device.
