I do think it is good practice to set pointers to null generally as that

The current dvb framework contain several other cases where pointers are
feed'd but not nulled.
There is kzfree() for that, but still I am very unsure should we start
zeroing memory upon release driver has allocated, or just relase it
using kfree.

Well I guess I am biased as I have spent lots of time finding a bug that
probably wouldn't exist if the policy was that drivers always should set
their memory to zero before it is free'd. Maybe we should have a compile
time override so that all free calls zeroes the memory before the actual
free? Maybe there already is this kind of feature?
