we are using AD5764, we have enabled AD5764 driver in linux driver configuration. 

we are able to write to out_voltage0_raw, out_voltage0_calibscale, out_voltage0_calibbias files.

When tried to read out_voltage0_scale, following error was observed. 

cat: read error: Invalid argument.

How do i resolve this error?
