^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  11)  * A deferred delay for thermal monitor is considered safe because:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  12)  * If the chip gets too hot during a sleep state it's most likely due to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  13)  * external factors, such as the surrounding temperature. I.e. no SW decisions
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  14)  * will make any difference.
