Hello
Is this patch slated to end up in one of the 4.13.x updates? It landed on v4.14-rc2 already but seems to have missed the 4.13.3 and 4.13.4 tagging.
Without this patch, I can't connect any USB Ethernet or the kernel will start producing that WARN_ON message and returning -EFAULT for quite a few programs.
