5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> [ Upstream commit 097d9d414433315122f759ee6c2d8a7417a8ff0f ] When the driver core calls pci_device_remove(), there is a driver bound to the device, so pci_dev->driver is never NULL. Remove the unnecessary test of pci_dev->driver.
