These issues currently affect mostly the output for /sys/bus/serial-base/devices, but need to be also fixed to avoid port addressing issues later on. It would be good to get these fixes into the -rc cycle to avoid folks possibly trying to use the incorrect sysfs port device names for finding uart ports for example.
