I think.....u can find the interfcae (IDE interface) to which the
STORAGE device is connected...not the device...
try this out...
static int __init i_m (void)
{
struct pci_dev *dev = NULL, *cdev = NULL;
struct pci_driver *ddev = NULL;
if (!pci_present ())
{
printk ("No pci device present\n");
return;
}
else
printk ("pci present\n");
while (1)
{
if ((dev = pci_find_device (PCI_ANY_ID, PCI_ANY_ID, dev)) == NULL)
{
printk (" end of storage devices\n");
break;
}
else
{
if ((dev->class >> 16 == PCI_BASE_CLASS_STORAGE))
{
printk ("%s ", dev->name);
printk ("%x ", dev->class);
printk ("%s ", pci_get_drvdata (dev));
ddev = dev->driver;
if (ddev == NULL) printk ("<null>\n");
else printk ("%s\n", ddev->name);
}
}
}
return 0;
}
static void __exit c_m (void)
{
printk ("\n*******************clean************\n");
}
module_init (i_m);
module_exit (c_m);
