Subject: Input: synaptics - skip quirks when post-2013 dimensions
From: Benjamin Tissoires <benjamin.tissoires@xxxxxxxxxx>
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.
