[PATCH 11/49] staging: comedi: cb_pcidas: use the pci id_table 'driver_data'
H Hartley Sweeten

Tue Mar 5 17:00:15 UTC 2013
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.
