From 4141127c44a9b00d941885fc41392697d22a62c3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 12 Oct 2021 16:37:55 -0500 Subject: [PATCH] powerpc/eeh: Use to_pci_driver() instead of pci_dev->driver MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Struct pci_driver contains a struct device_driver, so for PCI devices, it's easy to convert a device_driver * to a pci_driver * with to_pci_driver(). The device_driver * is in struct device, so we don't need to also keep track of the pci_driver * in struct pci_dev. Replace pdev->driver with to_pci_driver(). This is a step toward removing pci_dev->driver.
