7       present, 0 if not.

SYNOPSIS

10       int pci_dev_present(const struct pci_device_id * ids);
11

ARGUMENTS

13       ids
14           A pointer to a null terminated list of struct pci_device_id
15           structures that describe the type of PCI device the caller is
16           trying to find.
17

OBVIOUS FACT

19       You do not have a reference to any device that might be found by this
20       function, so if that device is removed from the system right after this
21       function is finished, the value will be stale. Use this function to
22       find devices that are usually built into a system, or for a general
23       hint as to if another device happens to be present at this specific
24       moment in time.
