|
|
|
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.
