You might want to start here then:

* DEFINE_PCI_DEVICE_TABLE - macro used to describe a pci device table
* @_table: device table name
* This macro is used to create a struct pci_device_id array (a device table)
* in a generic manner.
#define DEFINE_PCI_DEVICE_TABLE(_table) \
const struct pci_device_id _table[] __devinitconst
