[PATCH 3.16.y-ckt 028/144] Input: synaptics - support min/max board id in min_max_pnpid_table

From: Luis Henriques
Date: Tue Apr 21 2015 - 11:33:10 EST


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

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

From: Daniel Martin <daniel.martin@xxxxxxxxxxx>

commit 5b3089ddb540401c1ad2e385a03d7e89ff954585 upstream.

Add a min/max range for board ids to the min/max coordinates quirk. This
makes it possible to restrict quirks to specific models based upon their
board id. The define ANY_BOARD_ID (0) serves as a wild card.
