[ Upstream commit dc22c1c058b5c4fe967a20589e36f029ee42a706 ]
My 2TB SKC2000 showed the exact same symptoms that were provided in 538e4a8c57 ("nvme-pci: avoid the deepest sleep state on Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed cold boot to get it back.
According to some sources, the A2000 is simply a rebadged SKC2000 with a slightly optimized firmware.
Adding the SKC2000 PCI ID to the quirk list with the same workaround as the A2000 made my laptop survive a 5 hours long Yocto bootstrap buildfest which reliably triggered the SSD lockup previously.

Thanks for picking it up for stable.
May I suggest to include it in 5.10.x as well? Originally this patch was tested on 5.10.17.
Best regards, Zoltán Böszörményi
