pci_dev_get(9)
NAME
pci_dev_get - increments the reference count of the pci device
structure
SYNOPSIS
struct pci_dev * pci_dev_get(struct pci_dev * dev);
ARGUMENTS
- dev
- the device being referenced
DESCRIPTION
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.
