tracing: Have trace_buffer_unlock_commit() call the _regs version with NULL
There's no real difference between trace_buffer_unlock_commit() and trace_buffer_unlock_commit_regs() except that the former passes NULL to ftrace_stack_trace() instead of regs. Have the former be a static inline of the latter which passes NULL for regs. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
