[PATCH 3.16.y-ckt 025/144] Input: synaptics - log queried and quirked dimension values

From: Luis Henriques
Date: Tue Apr 21 2015 - 12:25:52 EST


3.16.7-ckt10 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Daniel Martin <consume.noise@xxxxxxxxx>

commit 9aff65982d0f58a78a27769fba7e97bc937b2593 upstream.

Logging the dimension values we queried and the values we use from a quirk
to overwrite can be helpful for debugging.

This partly relates to bug:
