My patch I mentioned:
[PATCH V4] nvmem: add explicit config option to read old syntax fixed OF 
cells

adds following line:
config.add_legacy_fixed_of_cells = of_device_is_compatible(node, 
"nvmem-cells");

So this is a false kernel bot warning (but I understand kernel bot
couldn't understand it needs my other patch).
