So moving the fallthrough; conversions inside the #ifdef/#endif block avoids this warning. These are the only warnings emitted on a treewide scripted conversion as found by the kernel-robot so applying these patches allows a treewide conversion, either as multiple discrete patches or a single large patch to eventually be done.
