Subject: [PATCH v3 07/12] PM / devfreq: export devfreq_class
Date: Thu, 14 Jun 2018 12:47:07 -0700	[thread overview]
Message-ID: <20180614194712.102134-8-mka@chromium.org> (raw)
In-Reply-To: <20180614194712.102134-1-mka@chromium.org>

Exporting the device class allows other parts of the kernel to enumerate
the devfreq devices and receive notification when a devfreq device is
added or removed.
