With all six patches from this set applied, each of the two functions
is called twice in the code. Together with the return value checks and
repeated error messages it bloats the code even more. What about a
single function taking the name of the register (in our case
"configuration" or "calibration") as argument in order to print a nice
error message? If this is still too dirty, than we can just print the
hex value of the register.
