Why a whole cdev? Why not use a misc device? YOu only have 2 devices right? Why not 2 misc devices then? That saves the use of a whole major number and makes your code a _LOT_ simpler.The downside would be that if we ever want to add sysfs attributes, that could not be done synchronously with the device creation.
That is what the groups member of struct misc_device is for. greg k-h
