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

You may want to CC Andrew Morton <akpm@linux-foundation.org>, who
tends to pick up patches for non-responsive architecture maintainers.

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 !!

Since v5.5-rc1 there is the fallthrough pseudo keyword to document
these cases:
