[ Upstream commit93d5e70015] In the stat-display code, it needs to check if the current evsel is hybrid but it uses perf_pmu__has_hybrid() which can return true for non-hybrid event too. I think it's better to use evsel__is_hybrid(). Also remove a NULL check for the 'config' parameter in the hybrid_merge() since it's called after config->no_merge check.

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.
