The above is talking about return values. Maybe you were trying to
reference this one as example about add_work() and
pci_dev_present():
For example, "add work" is a command, and the add_work()
function returns 0 for success or -EBUSY for failure. In the
same way, "PCI device present" is a predicate, and the
pci_dev_present() function returns 1 if it succeeds in finding a
matching device or 0 if it doesn't.
Seems make sense. Will take your advice. Thanks.
