There are packets which doesn't have a payload. In that case, the second

controller doesn't have any data left, it will NACK the I2C read and
-ENXIO will be returned. In case there is no payload, just skip the
second i2c master read.

Thanks, I'll reorder the patches in the next version otherwise
there will likely be a conflict. That should work with any patch
tools (i.e. b4), shouldn't it?
