PMU name is printed repeatedly for interval print, for example:
perf stat --no-merge -e 'unc_m_clockticks' -a -I 1000
# time counts unit events

For each print, the PMU name is unconditionally appended to the
counter->name.
Need to check the counter->name first. If the PMU name is already
appended, do nothing.
Committer notes:
Add and use perf_evsel->uniquified_name bool instead of doing the more
expensive strstr(event->name, pmu->name).

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.
