Subject: kconfig: qconf: move ConfigView::updateList(All) to ConfigList class
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f9b918fae678eacdeaad821db57a107fba6fe3a1;p=linux.git

kconfig: qconf: move ConfigView::updateList(All) to ConfigList class

ConfigView::updateList() iterates over all views, and then calls
updateList() against for its ConfigList instance.

This means there is no point to implement it in the ConfigView class.

Move and rename as follows:

  ConfigView::updateList()     -> ConfigList::updateListForAll()
  ConfigView::updateListAll()  -> ConfigList::updateListAllForAll()

I used QList to contain all ConfigList instances.
