[PATCH AUTOSEL 5.10 24/25] nvme-pci: add the IGNORE_DEV_SUBNQN quirk for Intel P4500/P4600 SSDs

[Sasha Levin]

From: Wu Zheng <wu.zheng at intel.com>

[ Upstream commit 25e58af4be412d59e056da65cc1cefbd89185bd2 ]

The Intel P4500/P4600 SSDs do not report a subsystem NQN despite claiming
compliance to a standards version where reporting one is required.

Add the IGNORE_DEV_SUBNQN quirk to not fail the initialization of a
second such SSDs in a system.
