Subject: [PATCH ftrace/core] tracing: Remove return value in event_trace_self_tests() when top_trace_array() returns NULL
Date: Fri, 06 Jun 2014 15:28:44 +0900 [thread overview]
Message-ID: <20140606062844.7955.61919.stgit@yunodevel> (raw)
In-Reply-To: <20140605234623.484afaf8@gandalf.local.home>
Remove return value in event_trace_self_tests() when top_trace_array() returns
NULL because event_trace_self_tests() is void type.
