In the dmesg is showing the message "failed to read out thermal zone" as if the temperature read is failed by don't find the thermal zone. After researching and debugging, I see that this specific error is occurrenced because the thermal try read the temperature when is started, but the firmware is not running yet. For more legibiliti i change the tt.c for return EAGAIN when this was occurrence. After this change, in my computer I compile and install kernel in /boot and in my dmesg the message "failed to read out thermal zone" is not show any more. I would like to thanks for Rafael Wysocki <refael.j.wysocki@intel.com> , Kalle Valo <kvalo@kernel.org> and Johannes Berg <johannes@sipsolutions.net> for your suggestions in my previous patch.
