Here is the output of nm for above two methods.


00000000 t pci_dev_put
00000000 t pci_get_device

It seems like their visibility is "local". I looked at the declaration
and the definition of the methods and they are not defined as "static" 

Here is the declaration for "pci_get_device"
--------
struct pci_dev *pci_get_device(unsigned int vendor, unsigned int device,
                                struct pci_dev *from);
--------

And here is the implementation
--------
struct pci_dev *
pci_get_device(unsigned int vendor, unsigned int device, struct pci_dev
*from)
{
        return pci_get_subsys(vendor, device, PCI_ANY_ID, PCI_ANY_ID,
from);
}
---------

I might not have the clear understanding of the problem here. I would
appreciate your help here.

Thanks,
Shashi
