Subject: [PATCH] include/linux/posix_acl.h: need 'return NULL' when BUG(),
 if neither CONFIG_BUG nor HAVE_ARCH_BUG is defined.


If neither CONFIG_BUG nor HAVE_ARCH_BUG is defined, the BUG() will
defined as empty (e.g. randconfig with MMU for arm s5pv210)

In this case, need 'return NULL' to let upper caller knows the failure.
