Subject: [PATCH 4.19 79/87] perf hists browser: Restore ESC as "Zoom out" of DSO/thread/etc

From: Arnaldo Carvalho de Melo <acme@...hat.com>

commit 3f7774033e6820d25beee5cf7aefa11d4968b951 upstream.

We need to set actions->ms.map since 599a2f38a989 ("perf hists browser:
Check sort keys before hot key actions"), as in that patch we bail out
if map is NULL.
