Hongbo Yao aa7baef530 perf stat: Fix NULL pointer dereference
[ Upstream commit c0c652fc705de75f4ba52e93053acc1ed3933e74 ]

If config->aggr_map is NULL and config->aggr_get_id is not NULL,
the function print_aggr() will still calling arrg_update_shadow(),
which can result in accessing the invalid pointer.

README

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.
