[6.7.x] Unable to Detect 2 NVME Drives (same model)

I am having this issue with 2 Adata XPG GAMMIX S5 256GB drives.  Both are seen in the BIOS but I see the following during system start up.

Jul 14 21:56:11 TheWatchtower kernel: nvme nvme1: ignoring ctrl due to duplicate subnqn (nqn.2018-05.com.example:nvme:nvm-subsystem-OUI00E04C).

Jul 14 21:56:11 TheWatchtower kernel: nvme nvme1: Removing after probe failure status: -22

Further digging I came across this *NEW* https://lkml.org/lkml/2019/7/15/57

Subject:  [PATCH] NVME: ignore subnqn for ADATA SX6000LNP

The ADATA SX6000LNP NVMe SSDs have the same subnqn and, due to this, a system with more than one of these SSDs will only have one usable.

[ 0.942706] nvme nvme1: ignoring ctrl due to duplicate subnqn (nqn.2018-05.com.example:nvme:nvm-subsystem-OUI00E04C).

[ 0.943017] nvme nvme1: Removing after probe failure status: -22

# lspci | grep Non-Volatile

02:00.0 Non-Volatile memory controller [0108]: Realtek Semiconductor Co., Ltd. Device [10ec:5762] (rev 01)

71:00.0 Non-Volatile memory controller [0108]: Realtek Semiconductor Co., Ltd. Device [10ec:5762] (rev 01)

There are no firmware updates available from the vendor, unfortunately. Applying the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk for these SSDs resolves the issue, and they all work after this patch:

# nvme list

/dev/nvme0n1 2J1120050420 ADATA SX6000LNP [...]

/dev/nvme1n1 2J1120050540 ADATA SX6000LNP [...]

and this (specific for the Adata drives that use the Realtek Controller) If I need to get more info please let me know

Running  lspci | grep Non-Volatile

I get

01:00.0 Non-Volatile memory controller: Realtek Semiconductor Co., Ltd. Device 5762 (rev 01)
23:00.0 Non-Volatile memory controller: Realtek Semiconductor Co., Ltd. Device 5762 (rev 01)

In a nut shell, if the system has 2 similar drives that don't have a unique NQN the system assumes its a duplicate and doesn't use it.

Cheers,
