Hi experts,
starting with linux kernel 5.4 my NVME SSD from HP is no longer detected
correctly, nvme list shows no result. I made no relevant changes
regarding .config between kernels 5.3 and 5.4.
Please have a look at this bugzilla entry:
https://bugzilla.kernel.org/show_bug.cgi?id=205679
Maybe all SSDs with a Silicon Motion 2263 controller are affected.
If you need more information, please ask.
Regards
Ingo Brunberg

It's a regression from commit 538af88ea7d9de241e6b6f006e9049c4d96723bb.
This one should have only returned the error if < 0, otherwise we can
proceed. Will get post a patch shortly with a 5.4 stable request.

Should we have something that is more granular rather than any positive
error?

I don't think so, otherwise we'll be chasing new errors from disfunctional
controllers. As long as we get a response of any kind, we can use the
controller. It's only when we don't get a response, which is what the
negative return codes are for.
