I performed another simple software refactoring.

I do not know at the moment why an error code which you find
questionable was suggested by Marco Chiappero on 2012-05-19
and committed by Matthew Garrett on 2012-05-31 (according the
commit d6f15ed876b83a1a0eba1d0473eef58acc95444a: use soft rfkill
status stored in hw).

Can any other identifier make more sense there?

The shown function call was repeated with an other parameter.
Which error reporting would you find more appropriate then?

Do we occasionally need to distinguish better between an ordinary
refactoring and the adjustments for additional software improvements?
