I have an issue where the ses driver no longer attaches. Last known

I would appreciate some details, like dmesg, error messages, etc. On my
test systems I see no problems.
Hi!
I did some more digging. r351355 is ok, while r351356 is bad. This is
Warner's (CC:d) commit to add RST support to nvme, however, I'm using a
ssd drive connected to ahci.
What happens is that the ses driver doesn't attach to the AHCI SGPIO
enclosure. This is on a laptop with an ssd (not an nvme) drive. I have
the same issue on another computer as well. On the broken kernel,
sesutil status complains about "No SES devices found", on the working
kernel it reports "ok".
I can confirm this behaviour (haven't checked versioning) .. working
kernel yields ..

Yeah, I'm seeing this also.
