Subject: tracing: Have HIST_TRIGGERS select TRACING

From: Tom Zanussi <[email protected]>

commit 7ad8fb61c4abf589596f0a4da34d987471481569 upstream.

The kbuild test robot reported a compile error if HIST_TRIGGERS was enabled but nothing else that selected TRACING was configured in.

HIST_TRIGGERS should directly select it and not rely on anything else to do it.

Fixes 7ef224d1d0e3a ("tracing: Add 'hist' event trigger command")
