Adrian Hunter bfba9722cf perf tools: Fix misleading add event PMU debug message 
[ Upstream commit f034fc50d3c7d9385c20d505ab4cf56b8fd18ac7 ]

Fix incorrect debug message:

   Attempting to add event pmu 'intel_pt' with '' that may result in
   non-fatal errors

which always appears with perf record -vv and intel_pt e.g.

    perf record -vv -e intel_pt//u uname

The message is incorrect because there will never be non-fatal errors.

Suppress the message if the PMU is 'selectable' i.e. meant to be
selected directly as an event.

Fixes: 4ac22b484d ("perf parse-events: Make add PMU verbose output clearer")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
