Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

See Bugzilla for the full thread.

The reporter had a quirk (see above) that fixed this regression,
nevertheless I'm adding it to regzbot to make sure it doesn't fall
through cracks unnoticed:

#regzbot introduced: 86c2457a8e8112f https://bugzilla.kernel.org/show_bug.cgi?id=217593
#regzbot title: NVME_QUIRK_BOGUS_NID is needed for SAMSUNG MZ1WV480HCGL-000MV

Thanks.
