Subject: [Very RFC 18/46] powernv/pci: Add pci_bus_to_pnvhb() helper
Date: Wed, 20 Nov 2019 12:28:31 +1100 [thread overview]
Message-ID: <20191120012859.23300-19-oohall@gmail.com> (raw)
In-Reply-To: <20191120012859.23300-1-oohall@gmail.com>
Add a helper to go from a pci_bus structure to the pnv_phb that hosts that
bus. There's a lot of instances of the following pattern:
struct pci_controller *hose = pci_bus_to_host(pdev->bus);
struct pnv_phb *phb = hose->private_data;
Without any other uses of the pci_controller inside the function. This is
hard to read since it requires you to memorise the contents of the
private data fields and kind of error prone since it involves blindly
assigning a void pointer. Add a helper to make it more concise and
explict.
