Subject: [PATCH v1 0/5] PCI: Drop duplicated tracking of a pci_dev's bound driver
Date: Thu, 29 Jul 2021 22:37:35 +0200 [thread overview]
Message-ID: <20210729203740.1377045-1-u.kleine-koenig@pengutronix.de> (raw)
Hello,
struct pci_dev tracks the bound pci driver twice. This series is about
removing this duplication.
The first two patches are just cleanups. The third patch introduces a
wrapper that abstracts access to struct pci_dev->driver. In the next
patch (hopefully) all users are converted to use the new wrapper and
finally the fifth patch removes the duplication.
Note this series is only build tested (allmodconfig on several
architectures).
I'm open to restructure this series if this simplifies things. E.g. the
use of the new wrapper in drivers/pci could be squashed into the patch
introducing the wrapper. Patch 4 could be split by maintainer tree or
squashed into patch 3 completely.
Best regards
Uwe
