3.19-stable review patch. If anyone has any objections, please let me know.

commit 02e07492cdfae9c86e3bd21c0beec88dbcc1e9e8 upstream.
Post-2013 Lenovo laptops provide correct min/max dimensions, which are different with the ones currently quirked. According to https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids are assigned in the post-2013 touchpads:
t440p/t440s: LEN0036 -> 2964/2962 t540p: LEN0034 -> 2964
Using 2961 as the common minimum makes these 3 laptops OK. We may need to update those values later if other pnp_ids has a lower board_id.
