[PATCH v2 0/3] Serial core controller port device name fixes

[Tony Lindgren <tony@atomide.com>]

A few issues have been found with device naming for the serial core
controller port device. 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.

Regards,

Tony
