+Subject: touchpad: only use negative pressure change check on Lenovo *50 and
+ *60 series
+
+This was introduced for bug 94379 - an X1 Carbon 3rd. Other touchpads have
+different pressure change ranges, causing this condition to trigger
+randomly and resulting in a jerky pointer motion.
+
+For now, reduce the check to the *50 and *60 series touchpads until we have
+data for more touchpads that we can add one-by-one.
