[PATCH -next] scsi: pmcraid: Use pci_dev_id() to simplify the code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



PCI core API pci_dev_id() can be used to get the BDF number for a pci
device. We don't need to compose it manually. Use pci_dev_id() to
simplify the code a little bit.
