Subject: [PATCH v2 4/6] PCI: Provide wrapper to access a pci_dev's bound driver
Date: Tue, 3 Aug 2021 12:01:48 +0200 [thread overview]
Message-ID: <20210803100150.1543597-5-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20210803100150.1543597-1-u.kleine-koenig@pengutronix.de>
Which driver a device is bound to is available twice: In struct
pci_dev::dev->driver and in struct pci_dev::driver. To get rid of the
duplication introduce a wrapper to access struct pci_dev's driver
member. Once all users are converted the wrapper can be changed to
calculate the driver using pci_dev::dev->driver.
