ECP update triggers bug in recent Linux kernels

I describe my t460s case, but the problem affects other systems as well. It seems that Embedded Controller Program (ECP) firmware revision 1.10 triggers some bug in Linux kernels starting from 4.9 series: the problem is that sometimes after suspend a sensor gives wrong temperature (stuck at 48C) and the fan goes on indefinitely, see this bug

Revision 1.9 instead works fine with every kernel.

 

Is it possible to communicate with someone in charge of this ECP, to look at changelog from previous version, and try to understand what is the issue with the new one?
