The ID table is an array of struct pci_device_id entries ending with an
all-zero entry. Each entry consists of:
all-zero entry; use of the macro DECLARE_PCI_DEVICE_TABLE is the preferred
method of declaring the table. Each entry consists of:
vendor,device Vendor and device ID to match (or PCI_ANY_ID)
......@@ -191,7 +192,8 @@ Tips on when/where to use the above attributes:
o Do not mark the struct pci_driver.
o The ID table array should be marked __devinitdata.
o The ID table array should be marked __devinitconst; this is done
automatically if the table is declared with DECLARE_PCI_DEVICE_TABLE().
o The probe() and remove() functions should be marked __devinit
and __devexit respectively. All initialization functions
