[PATCH] tracing: Move trace_iterator_increment() into trace_find_next_entry_inc()

[PATCH] tracing: Move trace_iterator_increment() into trace_find_next_entry_inc()

[Steven Rostedt]

From: Steven Rostedt <rostedt@goodmis.org>

trace_iterator_increment() is only called from trace_find_next_entry_inc().
It's a small enough function that really doesn't need to be separated.

Move the code from trace_iterator_increment() into
trace_find_next_entry_inc() and remove trace_iterator_increment().
