Hi Jaswinder,

Sorry but you are wrong here. When it comes to hardware monitoring (or
monitoring in general), potentially wrong data is _worse_ than no data
at all, unless you additionally carry the information that the data
value may be wrong, and display it in a very visible manner. As our
sysfs interface doesn't provide any way to pass reliability information
to the reader (and I don't think it would make sense to add one), it is
better to not export data that we know can't be trusted.
