This is more typical of how other drivers are written and removes the need for the forward declarations. Convert the driver to use the module_comedi_pci_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: H Hartley Sweeten Cc: Ian Abbott Cc: Mori Hess Cc: Greg Kroah-Hartman --- This is only a partial refactor. The attach/detach routines still need to be moved to remove the remaining forward declarations. drivers/staging/comedi/drivers/ni_pcimio.c | 192 ++++++++++++---------------- 1 files changed, 84 insertions(+), 108 deletions(-) diff --git a/drivers/staging/comedi/drivers/ni_pcimio.c b/drivers/staging/comedi/drivers/ni_pcimio.c index 1065b2c..9d0a08f 100644 --- a/drivers/staging/comedi/drivers/ni_pcimio.c +++ b/drivers/staging/comedi/drivers/ni_pcimio.c @@ -129,66 +129,6 @@ Bugs: #define DRV_NAME "ni_pcimio" -/* The following two tables must be in the same order */ -static DEFINE_PCI_DEVICE_TABLE(ni_pci_table) = { - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x0162)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1170)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1180)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1190)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x11b0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x11c0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x11d0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1270)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1330)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1340)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1350)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x14e0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x14f0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1580)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x15b0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1880)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x1870)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x18b0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x18c0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2410)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2420)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2430)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2890)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x28c0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2a60)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2a70)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2a80)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2ab0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2b80)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2b90)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2c80)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x2ca0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70aa)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70ab)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70ac)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70af)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70b0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70b4)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70b6)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70b7)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70b8)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70bc)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70bd)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70bf)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70c0)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x70f2)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x710d)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x716c)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x716d)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x717f)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x71bc)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x717d)}, - {PCI_DEVICE(PCI_VENDOR_ID_NI, 0x72e8)}, - {0} -}; - -MODULE_DEVICE_TABLE(pci, ni_pci_table); - /* These are not all the possible ao ranges for 628x boards.
