| 306 | This next batch of horrible preprocessor hackery is needed because the |
Kay Sievers | 54bd5b6 | 2007-10-08 16:26:13 -0300 | [diff] [blame] | 307 | kernel's device_attribute mechanism fails to pass the actual |
Mike Isely | d855497 | 2006-06-26 20:58:46 -0300 | [diff] [blame] | 308 | attribute through to the show / store functions, which means we have no |
| 309 | way to package up any attribute-specific parameters, like for example the |
| 310 | control id. So we work around this brain-damage by encoding the control |
| 311 | id into the show / store functions themselves and pick the function based |
| 312 | on the control id we're setting up. These macros try to ease the pain. |
| 313 | Yuck. |
