While porting over a few class_devices I discovered a problem with
device_destroy. It uses a dev_t which several classes don't use.
Should all classes require a dev_t or should we just pass in the device
itself?

As you don't have a dev_t, then you have a handle to the 'struct device'
itself, right? Then just call device_unregister(), that's all that
device_destroy() does after it finds the device in the list of devices
associated with the class.
Does this help?
thanks,

Okay. I needed to know if calling device_unregister directly was valid.
Thank you.
