------------------------------------------------------
Subject: Fix warnings for WARN_ON if CONFIG_BUG is disabled
From: Ralf Baechle <ralf@xxxxxxxxxxxxxx>
In most cases the return value of WARN_ON() is ignored. If the generic
definition for the !CONFIG_BUG case is used this will result in a warning:
CC kernel/sched.o
In file included from include/linux/bio.h:25,
from include/linux/blkdev.h:14,
from kernel/sched.c:39:
include/linux/ioprio.h: In function â??task_ioprioâ??:
include/linux/ioprio.h:50: warning: statement with no effect
kernel/sched.c: In function â??context_switchâ??:
kernel/sched.c:1834: warning: statement with no effect
