pci_dev_get — increments the reference count of the pci device structure
struct pci_dev * pci_dev_get ( | struct pci_dev * dev); |
Each live reference to a device should be refcounted.
Drivers for PCI devices should normally record such references in
their probe methods, when they bind to a device, and release
them by calling pci_dev_put, in their disconnect methods.
A pointer to the device with the incremented reference counter is returned.
