From: Adrian Hunter <adrian.hunter@intel.com>
commit f56299a9c998e0bfbd4ab07cafe9eb8444512448 upstream.
Deprecation warnings are useful only for the developer, not an end user. Display warnings only when requested using the python -W option. This stops the display of warnings like:
tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning: an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python. err = app.exec_()
Since the warning can be fixed only in PySide2, we must wait for it to be finally fixed there.
