If anyone has any objections, please let me know. ------------------ From: Georg Gottleuber commit eeaed48980a7aeb0d3d8b438185d4b5a66154ff9 upstream. On the TUXEDO InfinityBook S Gen8, a Samsung 990 Evo NVMe leads to a high power consumption in s2idle sleep (3.5 watts). This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with a lower power consumption, typically around 1 watts.
