/dev/port went missing in kernel 4.10.12. I think this is not by design because at least some tools depend on it? Reproducable: always
Can you explain what is broken for you by not having /dev/port on?
I use this to control the fanspeed of my HP Probook (BIOS has no good settings regarding this): https://github.com/k3mpaxl/fanspeed/blob/master/probook_ec.pl This relies on /dev/port. So no standard use case. Maybe I have to find another way then if possible.

Also sensors-detect from lm_sensors no longer works. It requires /dev/port to locate the ISA sensors.
I also ran across the file missing when trying to run https://github.com/nagisa/msi-rgb.
I solved my issue by finding a software that rather uses the "ec_sys" kernel module for that particular purpose: https://github.com/hirschmann/nbfc/blob/master/Core/Plugins/StagWare.Plugins.ECSysLinux/ECSysLinux.cs
Confirmed that sensors-detect in lm_sensors is broken due to this issue, on Fedora 26 as well.
