tracing: probeevent: Fix uninitialized used of offset in parse args
Dan's smatch utility found an uninitialized use of offset in a path in
parse_probe_args(). Unless an offset is specifically specified for commands
that allow them, it should default to zero.
Link: http://lkml.kernel.org/r/20181012134246.5doqaobxunlqqs53@mwanda
Fixes: 533059281ee5 ("tracing: probeevent: Introduce new argument fetching code")
