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. Thanks."
