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¶
struct pci_dev * 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.
