simpler alternatives would be making the userland program setuid
so that non root users can still access the devices,
or write a userland root demon to provide access via named pipes acting
like devices.
Or if you are going to do it in the kernel why not write a proper device
driver, one for the max197 used to be in the files section. It would make
a good template.
