Input: synaptics - log queried and quirked dimension values
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: https://bugzilla.kernel.org/show_bug.cgi?id=91541 Cc: stable@vger.kernel.org Signed-off-by: Daniel Martin <consume.noise@gmail.com> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
