Subject: [PATCH] psmouse: Add psmouse_matches_pnp_id helper function
The matches_pnp_id function from the synaptics driver is useful for other
drivers too. Make it a generic psmouse helper function.
Bugzilla: 1110011
Upstream-status: sent for 3.17/3.18
Signed-off-by: Hans de Goede <hdegoede@redhat.com>
