    Subject[PATCH AUTOSEL 5.3 33/33] nvme: Add quirk for Kingston NVME SSD running FW E8FK11.T
    Date
    From: Jian-Hong Pan <jian-hong@endlessm.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")
