A private data pointer in struct device_attribute allows the 'show' and 'store' functions to access instance data. This handy in situations where the driver_data and platform_data pointers of 'struct device' are already used for other purposes.

Greg, can you tell me if you think this patch is a good idea? It doesn't appear to do any harm, and I'm working on an ALSA driver that could benefit for this patch. I think 2.6.25 would be a good target.
