[ATM]: Fix dereference of uninitialized pointer in zatm
Fixing breakage from [NET]: Kill skb->list - original was
assign vcc
do a bunch of stuff using ZATM_VCC(vcc)->pool as common subexpression
Now we do
int pos = ZATM_VCC(vcc)->pool;
assign vcc
do a bunch of stuff
even though vcc is not even initialized when we enter that block...
