qt5base-lts/tests/auto/widgets/dialogs/qfilesystemmodel/tst_qfilesystemmodel.cpp
Marc Mutz 2fd3d8ea9e tests/auto/widgets: use QCOMPARE(., nullptr) 
.. instead of manually casted 0s.

QCOMPARE(., nullptr) was added for Qt 5.8. Make use of the new API.

In tst_qwidget.cpp, as a drive-by, change
   qApp->focusWidget() -> QApplication::focusWidget()
