[PATCH for-5.2 v2 3/9] pc-bios/s390-ccw: Introduce ENODEV define and remove guards of others
Remove the "#ifndef E..." guards from the defines here - the header guard S390_CCW_H at the top of the file should avoid double definition, and if the error code is defined in a different file already, we're in trouble anyway, then it's better to see the error at compile time instead of hunting weird behavior during runtime later. Also define ENODEV - we will use this in a later patch.
