I would guess that there is something wrong with the backporting of
my series - possibly a patch was dropped from the series?

"nvmem: core: fix cleanup after dev_set_name()" missing, which
initialises the struct device? But if that was missing, then
"nvmem: core: fix registration vs use race" wouldn't apply.

... but then you did send me a failure notice for the above
blamed commit, so I wonder how you applied it.
