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<mailto: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.

tacuser@fenderbmc:~# journalctl -u xyz.openbmc_project.fansensor.service
