From 97bcce5a4cf420986670c43923aa4bc5efa9bc2e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 5 Mar 2013 10:16:16 -0700 Subject: [PATCH] staging: comedi: ni_660x: use the pci id_table 'driver_data' Create an enum to the boardinfo and pass that enum in the pci_driver id_table as the driver_data. Change the macro used to fill in the device table from PCI_DEVICE() to PCI_VDEVICE(). This allows passing the enum as the next field. This allows removing the 'dev_id' data from the boardinfo as well the search function that was used to locate the boardinfo for the PCI device.
