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

[Kuninori Morimoto]

Hi Andrew

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

Is it possible to consider about it ?
SH compile will be error without this patch.

Thank you for your help !!
Best regards
