I'm trying to use next-20220422 and noticed a few new oops'es.
Turns out it could be a problem with this commit according to
[daniel@box linux.git]$ git bisect good
68471517e883902cdff6ea399d043b17f803b1a8 is the first bad commit
commit 68471517e883902cdff6ea399d043b17f803b1a8

mtd: call of_platform_populate() for MTD partitions
[...]
---
So when ever there is at least one 'compatible' node for any of the
mtd partitions I get the oops messages below. It doesn't really matter
what the compatible string is, "nvmem-cells" as well as "denx,fit"
(used for OpenWrt mtdsplit not even present in linux-next, so just a
dead hint in DTS) make the kernel to oops.
Despite the messages being shown, both accessing MTD partitions and
also eth0 MAC address populated via NVMEM seem to work without
problems (at least looks like it on first sight).
