-Subject: [PATCH] Die_CPU: filter first zero from GetTemp
-
-Peci command GetTemp can return 0 during CPU reset.
-It does not have a have completion code either.
-Discard the first zero reading and return -ENODATA.
-Consecutive zeros will be returned so that real hot
-condition will still be detected and logged but possibly delayed
-by the sensor polling period, which is normally 500ms-1s.
