There is a regression coming from:

nvmem: core: fix registration vs use race

which causes the following to happen for MTD devices:

[ 6.031640] kobject_add_internal failed for mtd0 with -EEXIST, don't
try to register things with the same name in the same directory.
[ 7.846965] spi-nor: probe of spi0.0 failed with error -17

attached is a full log with the call trace. This does not happen with
v6.2-rc8 where the MTD partitions are successfully registered.
