It'd be nicer to use consistent indentation for *name
in nvmem_cell

maybe rounddown() ?

and rounddown() here too ?

Perhaps more common as
d = bus_find_device(&nvmem_bus_type, NULL, nvmem_np, of_nvmem_match);
if (!d)
return NULL;
return to_nvmem_device(d);
}

odd indentation.
Normally, "read-only" would be aligned with nvmem->dev.of_node,

Isn't this going to have duplicated dev_name prefix and postfix?

Is the KERN_LEVEL correct?
Maybe dev_err/notice/warn/dbg?
