Notice that in this case, it's much clearer to explicitly add a break rather than letting the code to fall through. It also avoid potential future fall-through warnings[1]. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. [1] https://lore.kernel.org/patchwork/patch/1087056/ Signed-off-by: Gustavo A. R.
