[for-next][PATCH 11/12] tracing/kprobes: Remove unnecessary checking oftrace_probe_is_enabled

[Steven Rostedt]

From: "zhangwei(Jovi)" <jovi.zhangwei@xxxxxxxxxx>

Since tp->flags assignment was moved into function enable_trace_probe(),
there is no need to use trace_probe_is_enabled to check flags
in the same function.

Remove the unnecessary checking.
