tracing: trace_output.c, fix false positive compiler warning
This compiler warning: CC kernel/trace/trace_output.o kernel/trace/trace_output.c: In function ‘register_ftrace_event’: kernel/trace/trace_output.c:544: warning: ‘list’ may be used uninitialized in this function Is wrong as 'list' is always initialized - but GCC (4.3.2) does not recognize this relationship properly. Work around the warning by initializing the variable to NULL. [ Impact: fix false positive compiler warning ] Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
