Thanks for the series! Looks good to me. I believe both series can live
in separate tress, any reason why we would like to avoid this? I am keen
to apply [1] into the mtd tree rather soon.

I will handle the remaining deferral errors in the regular mtd path as
discussed on IRC.

Yes, I generated an initramfs with Buildroot, in which an overlay
containing the result of modules_install got merged (storage device =y
and nvmem layout to =m). I could observe the modprobe call being
successful and the layout driver being loaded early.
