Nicolai Stange 9561475db6 PCI: Fix race condition with driver_override ... The driver_override implementation is susceptible to a race condition when different threads are reading vs. storing a different driver override. Add locking to avoid the race condition. This is in close analogy to commit 6265539776 ("driver core: platform: fix race condition with driver_override") from Adrian Salido. Fixes: 782a985d7a ("PCI: Introduce new device binding path using pci_dev.driver_override") Signed-off-by: Nicolai Stange <nstange@suse.de> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Cc: stable@vger.kernel.org # v3.16+		2017-09-25 18:34:54 -05:00
