'perf script' in piped mode is crashing because evsel->priv is not set
properly. Fix it.
Before:
# perf record -o - -- ls | perf script
<SNIP 'ls' output>
Segmentation fault (core dumped)
#
After:
# perf record -o - -- ls | perf script
<SNIP 'ls' output>
ls 2282 1031.731974: 250000 cpu-clock:uhH: 7effe4b3d29e
ls 2282 1031.732222: 250000 cpu-clock:uhH: 7effe4b3a650

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
