Hi Lukas, Sorry to disturb you. We encountered a deadlock between reset_lock semaphore and device_lock (dev->mutex) in linux-4.19. After some searching, we found the fix you suggested about the same question [1]. We wonder if there are new versions of this patch? If so, would you mind submitting it for upstream branch?
