13e45417ce checkpatch: fix the usage of capture group ( ... )
The usage of "capture group (...)" in the immediate condition after `&&`
results in `$1` being uninitialized.  This issues a warning "Use of
uninitialized value $1 in regexp compilation at ./scripts/checkpatch.pl
line 2638".

I noticed this bug while running checkpatch on the set of commits from
v5.7 to v5.8-rc1 of the kernel on the commits with a diff content in
their commit message.

This bug was introduced in the script by commit e518e9a59e
("checkpatch: emit an error when there's a diff in a changelog").  It
has been in the script since then.

The author intended to store the match made by capture group in variable
`$1`.  This should have contained the name of the file as `[\w/]+`
matched.  However, this couldn't be accomplished due to usage of capture
group and `$1` in the same regular expression.

Fix this by placing the capture group in the condition before `&&`.
Thus, `$1` can be initialized to the text that capture group matches
thereby setting it to the desired and required value.

The documentation also says:
"Warning: We do not recommend using QString::asprintf() in new Qt code.
Instead, consider using QTextStream or arg(), both of which support
Unicode strings seamlessly and are type-safe."

Use QTextStream as suggested.

53efe2e76c kconfig: qconf: remove qInfo() to get back Qt4 support
qconf is supposed to work with Qt4 and Qt5, but since commit
c4f7398bee ("kconfig: qconf: make debug links work again"),
building with Qt4 fails as follows:

  HOSTCXX scripts/kconfig/qconf.o
scripts/kconfig/qconf.cc: In member function ‘void ConfigInfoView::clicked(const QUrl&)’:
scripts/kconfig/qconf.cc:1241:3: error: ‘qInfo’ was not declared in this scope; did you mean ‘setInfo’?

      |   setInfo
make[1]: *** [scripts/Makefile.host:129: scripts/kconfig/qconf.o] Error 1
make: *** [Makefile:606: xconfig] Error 2

qInfo() does not exist in Qt4. In my understanding, these call-sites
should be unreachable. Perhaps, qWarning(), assertion, or something
is better, but qInfo() is not the right one to use here, I think.

I do not know when ConfigInfoView::createStandardContextMenu() is

Because QTextEdit::createStandardContextMenu() is not virtual,
ConfigInfoView::createStandardContextMenu() cannot override it.

menu does not show up.

d85de3399f kconfig: qconf: fix signal connection to invalid slots
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:  (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.

fa8de0a3bf kconfig: qconf: do not limit the pop-up menu to the first row
If you right-click the first row in the option tree, the pop-up menu
shows up, but if you right-click the second row or below, the event
is ignored due to the following check:

  if (e->y() <= header()->geometry().bottom()) {

Perhaps, the intention was to show the pop-menu only when the tree
header was right-clicked, but this handler is not called in that case.

Since the origin of e->y() starts from the bottom of the header,
this check is odd.

Going forward, you can right-click anywhere in the tree to get the
pop-up menu.

ced69da1db checkpatch: fix CONST_STRUCT when const_structs.checkpatch is missing
Checkpatch reports warnings when some specific structs are not declared as
const in the code.  The list of structs to consider was initially defined
in the checkpatch.pl script itself, but it was later moved to an external
file (scripts/const_structs.checkpatch), in commit bf1fa1dae6
("checkpatch: externalize the structs that should be const").  This
introduced two minor issues:

- When file scripts/const_structs.checkpatch is not present (for
  example, if checkpatch is run outside of the kernel directory with the
  "--no-tree" option), a warning is printed to stderr to tell the user
  that "No structs that should be const will be found". This is fair,
  but the warning is printed unconditionally, even if the option
  "--ignore CONST_STRUCT" is passed. In the latter case, we explicitly
  ask checkpatch to skip this check, so no warning should be printed.

- When scripts/const_structs.checkpatch is missing, or even when trying
  to silence the warning by adding an empty file, $const_structs is set
  to "", and the regex used for finding structs that should be const,
  "$line =~ /struct\s+($const_structs)(?!\s*\{)/)", matches all
  structs found in the code, thus reporting a number of false positives.

Let's fix the first item by skipping scripts/const_structs.checkpatch
processing if "CONST_STRUCT" checks are ignored, and the second one by
skipping the test if $const_structs is not defined. Since we modify the
read_words() function a little bit, update the checks for
$typedefsfile/$typeOtherTypedefs as well.
