Geert Uytterhoeven 6a7228d90d ARM: amba: 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 this race condition. Cfr. commits 6265539776 ("driver core: platform: fix race condition with driver_override") and 9561475db6 ("PCI: Fix race condition with driver_override"). Fixes: 3cf3857134 ("ARM: 8256/1: driver coamba: add device binding path 'driver_override'") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Todd Kjos <tkjos@google.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-04-26 10:35:04 +02:00
