| 304 | This next batch of horrible preprocessor hackery is needed because the |
| 305 | kernel's class_device_attribute mechanism fails to pass the actual |
| 306 | attribute through to the show / store functions, which means we have no |
| 307 | way to package up any attribute-specific parameters, like for example the |
| 308 | control id. So we work around this brain-damage by encoding the control |
| 309 | id into the show / store functions themselves and pick the function based |
| 310 | on the control id we're setting up. These macros try to ease the pain. |
| 311 | Yuck. |
