Subject[PATCH 7/7] perf annotate: Add missing newline on error message
Date
From: Namhyung Kim <namhyung.kim@lge.com>

If perf.data couldn't find vmlinux image for the given build-id,
it would print error message. However it lacked a newline at the
end, so the output looked like below:

$ perf annotate --stdio
No vmlinux file with build id 63b554b2e90f14a4bced200008865e757d3e8b36
was found in the path.

Please use:

perf buildid-cache -av vmlinux

or:

--vmlinux vmlinux Percent | Source code & Disassembly of a.out

0.00 : 400520: leaveq
0.00 : 400521: retq

Fix it by adding a newline at the end of the message. It doesn't affect
the tui output AFAICS. New output will look like this:

...
or:

--vmlinux vmlinux
