Subject: [PATCH 1/3] PCI: add helper pci_dev_id
Date: Fri, 19 Apr 2019 13:08:52 +0200 [thread overview]
Message-ID: <8e0ebcd1-e448-67a1-d4e8-bc955d895feb@gmail.com> (raw)
In-Reply-To: <b352964f-a9a4-c8eb-520c-19b4dca4fba1@gmail.com>
In several places in the kernel we find PCI_DEVID used like this:
PCI_DEVID(dev->bus->number, dev->devfn) Therefore create a helper
for it.
