this should be a replacement for

 drivers: net: hso: hack to avoid NULL pointer dereferencing - the reason is unknown. Perhaps some race condition in the USB stack?

I cannot reproduce the problem here even without that hack patch. There
was some dhcpd running? How was it started?
A recent backtrace forthe commit message would also be nice when I
try to upstream this.

Regards,
Andreas
