kconfig: qconf: clean deprecated warnings
The recommended way to initialize a null string is with QString(). This is there at least since Qt5.5, with is when qconf was ported to Qt5. Fix those warnings: scripts/kconfig/qconf.cc: In member function ‘void ConfigItem::updateMenu()’: scripts/kconfig/qconf.cc:158:31: warning: ‘QString::null’ is deprecated: use QString() [-Wdeprecated-declarations] 158 | setText(noColIdx, QString::null); | ^~~~ In file included from /usr/include/qt5/QtCore/qobject.h:47, from /usr/include/qt5/QtWidgets/qwidget.h:45, from /usr/include/qt5/QtWidgets/qmainwindow.h:44, from /usr/include/qt5/QtWidgets/QMainWindow:1, from scripts/kconfig/qconf.cc:9: Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
