Subject: fansensor errors
Hello,
I am newbie with the OpenBMC. We are porting OpenBMC for a platform which has 7 fan modules with two fans in each module. I defined the
pwm-tacho-controller@1e786000.conf, and when I run it, I see the following errors from the fansenor service. Here I pasted logs from the service, my conf file and other important information. I did not
understand why the service is giving these errors. Appreciate your help.

[Thu Nguyen]: It seem you are setting VIRTUAL-RUNTIME_obmc-sensors-hwmon?=”dbus-sensors”, but your configuration is for phosphor-hwmon.
Above log is from dbus-sensors.
