Subject: [PATCH v3 0/8] PCI: Drop duplicated tracking of a pci_dev's bound driver
From: Uwe Kleine-König <uwe@...ine-koenig.org>
Hello,
Today the following is always true for a struct pci_dev *pdev:
pdev->driver ==
pdev->dev.driver ? to_pci_driver(pdev->dev.driver) : NULL
This series is about getting rid of struct pci_dev::driver. The first
three patches are unmodified compared to v2 (apart from an added
Reviewed-by tag) and are just minor cleanups.
Patch #4 replaces all usages of pci_dev::driver->name by
dev_driver_string().
Patch #5 simplifies struct mpt_pci_driver by dropping an unused
parameter from a function callback. The calculation of this parameter
made use of struct pci_dev::driver.
Patch #6 simplifies adf_enable_aer() and moves one assignment done in
that function to the initializer of the respective static data.
Patch #7 then modifies all remaining users of struct pci_dev::driver to
use to_pci_driver(pdev->dev.driver) instead and finally patch #8 gets
rid of the driver member.
Note this series is only build tested.
Theoretically patches #4 and #7 could be split by subsystem, there are
no dependencies, but I'd prefer that all patches go in together via the
pci tree to simplify the procedure. If you don't agree please speak up.
Best regards
Uwe
