[PATCH][resend] sh: kgdb: Mark expected switch fall-throughs

[Kuninori Morimoto]

Hi Greg

I'm posting this patch from few month ago,
but it seems SH ML maintainer is not working in these days...

I'm not sure who can handle this patch in this case,
but is it possible to consider about it ?

Thank you for your help !!
Best regards
