Subject: [PATCH 5.3 022/197] nvme: Add quirk for Kingston NVME SSD running FW E8FK11.T

From: Jian-Hong Pan <jian-hong@...lessm.com>

[ Upstream commit 19ea025e1d28c629b369c3532a85b3df478cc5c6 ]

Kingston NVME SSD with firmware version E8FK11.T has no interrupt after
resume with actions related to suspend to idle. This patch applied
NVME_QUIRK_SIMPLE_SUSPEND quirk to fix this issue.

Fixes: d916b1be94b6 ("nvme-pci: use host managed power state for suspend")
