Pull tracing fix from Steven Rostedt:
 "Fix wrong uprobe variable in iterator

  uprobe_perf_open() processes a list of probes, but due to a missing
  setting of the uprobe to be processed, the loop processes the head
  probe instead of the added probes"

* tag 'trace-v5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  tracing/uprobe: Fix uprobe_perf_open probes iteration
