A few issues have been found with device naming for the serial core
controller port device. These issues currently mostly affect the output
for /sys/bus/serial-base/devices, but need to be also fixed to avoid
port addressing issues later on.
Changes since v4:
- Make the sysfs device names nicer with DEVNAME:0.0 naming, the "ctrl"
and "port" prefixes are not needed with the controller id in the name
- Fix Andy's Reviewed-by as noted by Andy
- Generate patches with --patience to make the last patch more readable
Changes since v3:
- Drop unnecessary else on the return path in serial_base_device_init()
as noted by Andy
- Add Andy's Reviewed-by
- Update patch description for port_id instead of port port_id for the
first patch
Changes since v2:
- Fix my email script as it had started to drop linux-serial as noted by
Greg
- Explain why we're changing ctrl_id as requested by Greg
Changes since v1:
- Port id cannot be negative as noted by Jiri
- Controller id cannot be negative as noted by Andy
- Port name is missing the controller instance as noted by Andy
