Subject: [PATCH 2/2] thermal: Use emergency_poweroff instead of orderly_poweroff for shutdown scenario
Currently when the system reaches dangerously high temperatures we are
calling orderly_poweroff function to gracefully shutdown the user space
and then power off the system. In the probe phase the orderly_poweroff
might fail leaving the system running at dangerously high temperatures.
Hence calling the emergency_poweroff function which shuts down the
system after a configurable period of time.
