I don't know which meta-QT5 had 'dufell' :) but 'dunfell' branch in https://github.com/meta-qt5/meta-qt5 has 5.15 only in master branch and dunfell will stay on 5.14.*, but the 0005-Fix-build-with-Qt-5.15.patch seems to be backwards compatible, I guess it does no harm backporting this and might be useful for someone (as people are often mixing different meta-qt5 branches when they needs specific Qt release for whatever reason)
