Hi Everyone,

This is the second iteration of the $subject patch series and its original
description below is still applicable

This update is mostly related to the observation that the critical and hot trip
points never change after initialization, so they don't really need to be
connected back to the corresponding thermal_trip structures.  It also fixes
an error code path memory leak in patch [5/8].

Thanks!
