The root cause is that the thermal zone is register too early. Patch 1/3 is new in v2 and removes a unneeded call to set_trips() when resuming from suspend, This call was in v1 changed as part of addressing the initialization issue, it's nicer to get rid of it before that is needed. Patch 2/3 prepares for the change while also fixing a theoretical issue where one thermal node described in DT would describe interrupts and another would not. Resulting in interrupt support being disabled for both of them. I'm not aware of any case where this configuration would be used, either the SoC supports interrupts, or it don't. While patch 3/3 fixes the real issue by fully initializing the device before registering the zone.
