In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
Signed-off-by: Gustavo A. R. Silva <garsi...@embeddedor.com> --- This code was tested by compilation only (GCC 7.2.0 was used). Please, verify if the actual intention of the code is to fall through. Changes in v2: Start every "Fall through" comment with capital 'F'.
