Subject: [PATCH] sh: bug: add unreachable() to silence warnings
SuperH BUG() have warnings like
kernel/sched/core.c:2692:1: warning: control reaches end of non-void function
[-Wreturn-type]
net/core/ethtool.c:236:1: warning: control reaches end of non-void function
[-Wreturn-type]
Other BUG() implementations
have added unreachable() at end becuase of which I guess
it does not showthese errors. We can silence them using unreachable().
