The .suspend() and .resume() callbacks are not defined for this driver.
Still, their power management structure follows the legacy framework. To
bring it under the generic framework, simply remove the binding of
callbacks from "struct pci_driver".

FWIW, this commit log is slightly misleading because .suspend and
.resume are NULL by default, so this patch actually is a complete
no-op as far as code generation is concerned.

This change is worthwhile because it simplifies the code a little, but
it doesn't convert the driver from legacy to generic power management.
This driver doesn't supply a .pm structure, so it doesn't seem to do
*any* power management.

Agreed. Actually, as their presence only causes PCI core to call
pci_legacy_suspend/resume() for them, I thought that after removing the binding
from "struct pci_driver", this driver qualifies to be grouped under genric
framework, so used "use generic power management" for the heading.

I should have written "remove legacy bindning".

But David has applied the patch, should I send a v2 or fix to update message?

Thanks

Change code indentation from space to tab in "struct pci_driver".
