Hiraku Toyooka a54164114b tracing: Add checks if tr->buffer is NULL in tracing_reset{_online_cpus} ... max_tr->buffer could be NULL in the tracing_reset{_online_cpus}. In this case, a NULL pointer dereference happens, so we should return immediately from these functions. Note, the current code does not call tracing_reset*() with max_tr when its buffer is NULL, but future code will. This patch is needed to prevent the future code from crashing.
