As 'zero' can be a perfectly good id, it can be picked up as

Use idr kernel library to send/receive node ids to the
user instead of kernel address.
This id will be use to access the node handles at the

When dsp_notifications array is received from user,
dspbridge verifies the array has valid pointers
and dsp_notification structures. However, these
structures contain pointers that need to be
checked for valid handles.
