In preparation to limit the scope of the list iterator variable to the
traversal loop, use a dedicated pointer to point to the found element
[1].

v1->v2:
- fix NULL ptr dereference in subsystem_open() (Steven Rostedt)
- don't use the iterator in PATCH 3/4 when not necessary (Steven Rostedt)

Jakob Koschel (4):
  tracing: Remove usage of list iterator after the loop body
  tracing: Remove usage of list iterator variable after the loop
  tracing: Replace usage of found with dedicated list iterator variable
  tracing: Remove check of list iterator against head past the loop body
