From: H Hartley Sweeten Date: Tue, 5 Mar 2013 17:01:59 +0000 (-0700) Subject: staging: comedi: dt3000: use the pci id_table 'driver_data' X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cf7df5864aaac1af20ddc99f3d7b2ce94c5e27e1;p=linux-beck.git staging: comedi: dt3000: 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 'device_id' data from the boardinfo as well the search function that was used to locate the boardinfo for the PCI device. Since the PCI device ids are now only used in the id_table, remove the defines and open code the device ids.
