[PATCH 5/5] Input: synaptics - Support min/max board id in min_max_pnpid_table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 wildcard.
