Subject: [PATCH 2/3] psmouse: Add psmouse_matches_pnp_id helper function
Date: Thu, 11 Sep 2014 10:50:46 +0200	[thread overview]
Message-ID: <1410425447-9575-2-git-send-email-hdegoede@redhat.com> (raw)
In-Reply-To: <1410425447-9575-1-git-send-email-hdegoede@redhat.com>

The matches_pnp_id function from the synaptics driver is useful for other
drivers too. Make it a generic psmouse helper function.
