Subject: perf tools: Fix cache event name generation
From: Jiri Olsa <[email protected]>
commit 275ef3878f698941353780440fec6926107a320b upstream.
If the event name is specified with all 3 components, the last one
overwrites the previous one during the name composing within the
parse_events_add_cache function.
Fixing this by properly adjusting the string index.
