NAME
       pci_get_class - begin or continue searching for a PCI device by class

SYNOPSIS
       struct pci_dev * pci_get_class(unsigned int class, struct pci_dev * from);

ARGUMENTS
       class
           search for a PCI device with this class designation

       from
           Previous PCI device found in search, or NULL for new search.

DESCRIPTION
       Iterates through the list of known PCI devices. If a PCI device is found with a matching
       class, the reference count to the device is incremented and a pointer to its device
       structure is returned. Otherwise, NULL is returned. A new search is initiated by passing
       NULL as the from argument. Otherwise if from is not NULL, searches continue from next
       device on the global list. The reference count for from is always decremented if it is not
       NULL.
