In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly adding a couple break statements and replacing /* fall through */ comments with the new pseudo-keyword macro fallthrough; instead of just letting the code fall through to the next case. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R.
