Subject: [PATCH 4.19 55/71] kconfig: qconf: fix signal connection to invalid slots

From: Masahiro Yamada <masahiroy@...nel.org>

[ Upstream commit d85de3399f97467baa2026fbbbe587850d01ba8a ]

If you right-click in the ConfigList window, you will see the following
messages in the console:

QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:888
QObject::connect:  (sender name:   'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:897
QObject::connect:  (sender name:   'config')
QObject::connect: No such slot QAction::setOn(bool) in scripts/kconfig/qconf.cc:906
QObject::connect:  (sender name:   'config')

Right, there is no such slot in QAction. I think this is a typo of
setChecked.

Due to this bug, when you toggled the menu "Option->Show Name/Range/Data"
the state of the context menu was not previously updated. Fix this.

Fixes: d5d973c3f8a9 ("Port xconfig to Qt5 - Put back some of the old implementation(part 2)")
