-
- This next batch of horrible preprocessor hackery is needed because the
- kernel's device_attribute mechanism fails to pass the actual
- attribute through to the show / store functions, which means we have no
- way to package up any attribute-specific parameters, like for example the
- control id. So we work around this brain-damage by encoding the control
- id into the show / store functions themselves and pick the function based
- on the control id we're setting up. These macros try to ease the pain.
- Yuck.
