Jenkins has reported a build failure (https://build.kde.org/job/kcoreaddons%20master%20kf5-qt5/PLATFORM=Linux,compiler=gcc/117/console), looks like we might have dueling compiler errors:

    18:07:28 /home/jenkins/builds/kcoreaddons/kf5-qt5/src/lib/io/kdirwatch.cpp:137:1: error: control reaches end of non-void function [-Werror=return-type]

Seems that the GCC used on CI doesn't recognize that every possible error case is handled in the switch (or alternately, it assumes that someone might try to shoehorn an out-of-range enumeration value into the function). GCC 5.3 works fine, which is what I'd used for testing. But it might be easier to revert the switch/case portions of the patch, perhaps add warning suppressions instead?
