Nicolai Stange b08dc7d4cf PCI: Fix race condition with driver_override ... commit 9561475db6 upstream. 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.
