static struct pci_driver unknown field 'name' "has initializer but incomplete type"
 

I am writing a PCI device driver in gnu gcc

The includes are:


#include <linux/kernel.h>
#include <pci/config.h>
#include "/usr/src/kernels/2.6.27.21-170.2.56.fc10.i686/include/linux/pci.h"
#include <stdio.h>
#include <stdlib.h>

//#include <unistd.h>
//#include <linux/types.h>
#include <sys/types.h>
//#include <sys/stat.h>
#include <fcntl.h>
#include <string.h>
#include <errno.h>
#include <ctype.h>




The

static struct pci_device_id
NHI_15504_idtable [] = {
{ vendor : NHI_15504_VENDOR_ID,
device : NHI_15504_DEVICE_ID,
subvendor : PCI_ANY_ID,
subdevice : PCI_ANY_ID,
class : 0,
class_mask : 0,
driver_data :0,
},
{0,},
};


compiles cleanly. I have stubbed out the probe callback function.
The problem arises in the declaration of the


static struct pci_driver NHI_15504_driver = {
.name = "NHI_15504",
.id_table = NHI_15504_idtable,
.probe = &NHI_15504_probe,
.remove = NULL,

};

I get the following errors

Questions:
1) The Error

mod_devicetable.h:310: error: ‘BITS_PER_LONG’ undeclared here (not in a function)

The BITS_PER_LONG are define in file2alias.c as as result of

#if KERNEL_ELFCLASS == ELFCLASS32

(a) Where should KERNEL_ELFCLASS be #defined?
(b) Should it not be define already??

2) The Error

../NHI_15504.c:91: error: variable ‘NHI_15504_driver’ has initializer but incomplete type

(a) What am I missing in this struct declaration?
(b) Why are the fields 'name', ‘id_table’ 'probe" 'remove' unknown fields in this struct?
