[PATCH] openpromfs: factorize out
[PATCH] openpromfs: factorize out

"Move" "common code" out to PTR_NOD, which does the conversion from private
pointer to node number.  This is to reduce potential casting/conversion errors
due to redundancy.  (The naming PTR_NOD follows PTR_ERR, turning a pointer
into xyz.)
