+Subject: nvme-pci: Add sleep quirk for Samsung 990 Evo
+
+From: Georg Gottleuber <ggo@tuxedocomputers.com>
+
+commit 61aa894e7a2fda4ee026523b01d07e83ce2abb72 upstream.
+
+On some TUXEDO platforms, a Samsung 990 Evo NVMe leads to a high
+power consumption in s2idle sleep (2-3 watts).
+
+This patch applies 'Force No Simple Suspend' quirk to achieve a
+sleep with a lower power consumption, typically around 0.5 watts.
