tracing: initialize return value for __ftrace_set_clr_event
Commit 8f31bfe538ebafac187d2d4465a92e1d9ee6d8c2 tracing/events: clean up for ftrace_set_clr_event() Moved out the code for ftrace_set_clr_event into a helper funciton but did not initialize the return value. As a result, we do not warn about a typo in the echoing of events in set_event. This patch restores the old warning: # echo foobar > set_event -bash: echo: write error: Invalid argument [ Impact: restore warning of invalid entries to set_event ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
