Hello Jianjun,
there's only one last bit to fix, check below:

device_property_read_bool() returns device_property_present().

I would prefer that, instead, you call the latter:

	nvmem_enabled = device_property_present(dev, "nvmem-cells");

It's the same, yes, but this will increase human readability, as the function
name clearly states the intention here.

Thanks,
