The purpose was described here:

http://article.gmane.org/gmane.linux.scsi/54155

Basically we'd like to instruct user-space to retrieve a blob of data
automatically. Original implementation used the kboject hanging off
the module which does not exist when CONFIG_MODULES=n. It was
suggested that perhaps an alternative would be to use 'struct device'
kobj. Any tips on how to trigger such a driver-specific event,
perhaps a dedicated kobject exported by the driver itself???
