If anyone has any objections, please let me know. ------------------ From: Georg Gottleuber commit dbf2bb1a1319b7c7d8828905378a6696cca6b0f2 upstream. On the TUXEDO InfinityFlex, a Samsung 990 Evo NVMe leads to a high power consumption in s2idle sleep (4 watts). This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with a lower power consumption, typically around 1.4 watts.
