Now that you have a cdev these files may be more logically placed
under the cdev's sysfs and not under kernel? This can be done easially
using the attribute mechanisms in the struct device.
Again sort of back to my earlier point that everything should be
logically linked to the cdev as though there could be many cdevs, even
though there are not. It just keeps the code design more properly
layered and understanble rather than doing something unique..
