Subject: [PATCH] sh: bug: add unreachable() to silence warnings
Date: Thu, 07 Aug 2014 01:42:20 +0000 [thread overview]
Message-ID: <1407375741-3209-1-git-send-email-xerofoiify@gmail.com> (raw)
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().
