Subject: PCI: Drop pci_device_remove() test of pci_dev->driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 097d9d414433315122f759ee6c2d8a7417a8ff0f
Patch-mainline: 5.16-rc1
References: git-fixes

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.
