Subject: [PATCH v4 0/8] PCI: Drop duplicated tracking of a pci_dev's bound driver
Date: Mon, 27 Sep 2021 22:43:18 +0200	[thread overview]
Message-ID: <20210927204326.612555-1-uwe@kleine-koenig.org> (raw)

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Hello,

this is v4 of the quest to drop the "driver" member from struct pci_dev
which tracks the same data (apart from a constant offset) as dev.driver.

Changes since v3:
 - Add some Reviewed-by and Acked-by tags
 - Rebase to v5.15-rc3 (no conflicts)
 - Changes in patch #4 addressing review comments by Christoph Hellwig

I didn't do extensive build tests, so I might have missed a build
problem. I have some builds running, but want to get some feedback on
the changes suggested by Christoph.

Best regards
Uwe

  xen/pci: Drop some checks that are always true
  PCI: replace pci_dev::driver usage that gets the driver name
  scsi: message: fusion: Remove unused parameter of mpt_pci driver's
    probe()
  crypto: qat - simplify adf_enable_aer()
  PCI: Replace pci_dev::driver usage by pci_dev::dev.driver
