From f1469e568bf6dcbdff9fd7cd7d2cc9ca9d06efeb Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 6 Jul 2021 16:05:26 -0500 Subject: [PATCH] Input: Fix fall-through warning for Clang In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by explicitly adding a fallthrough; statement. Notice that this seems to be a Duff device for performance[1]. So, although the code looks a bit _funny_, I didn't want to refactor or modify it beyond merely adding a fallthrough marking, which might be the least disruptive way to fix this issue.
