   4 Subject: [PATCH] thermal/core: Add thermal_zone_device structure 'type'
   5  accessor
   6
   7 The thermal zone device structure is exposed via the exported
   8 thermal.h header. This structure should stay private the thermal core
   9 code. In order to encapsulate the structure, let's add an accessor to
  10 get the 'type' of the thermal zone.
