It added one to uart_shutdown(), so  \nthe commit assumes, uport can be NULL in there. But right after that  \nprotection, there is an unprotected \"uart_port_dtr_rts(uport, false);\"  \ncall. That is invoked only if HUPCL is set, so I assume that is the  \nreason why we do not see lots of these reports.  \n  \nOr it cannot be NULL at this point at all for some reason :P.  \n  \nUntil the above is investigated, stay on the safe side and move this  \ndereference to the if too.  \n  \nI got this inconsistency from Coverity under CID 1585130.
