2569 | * lpfc_pci_probe_one: lpfc PCI probe func to register device to PCI subsystem. | |
2570 | * @pdev: pointer to PCI device | |
2571 | * @pid: pointer to PCI device identifier | |
2572 | * | |
2573 | * This routine is to be registered to the kernel's PCI subsystem. When an | |
2574 | * Emulex HBA is presented in PCI bus, the kernel PCI subsystem looks at | |
2575 | * PCI device-specific information of the device and driver to see if the | |
2576 | * driver state that it can support this kind of device. If the match is | |
2577 | * successful, the driver core invokes this routine. If this routine | |
2578 | * determines it can claim the HBA, it does all the initialization that it | |
2579 | * needs to do to handle the HBA properly. | |
2580 | * | |
2581 | * Return code | |
2582 | * 0 - driver can claim the device | |
2583 | * negative value - driver can not claim the device | |
