Subject: [PATCH net-next 1/2] libceph: suppress crush_choose_indep()
 kernel-doc warnings

Currently, when built with "make W=1", the following warnings are
generated:
net/ceph/crush/mapper.c:655: warning: Function parameter or struct member 'map' not described in 'crush_choose_indep'
net/ceph/crush/mapper.c:655: warning: Function parameter or struct member 'work' not described in 'crush_choose_indep'

net/ceph/crush/mapper.c:655: warning: Function parameter or struct member 'out2' not described in 'crush_choose_indep'
net/ceph/crush/mapper.c:655: warning: Function parameter or struct member 'parent_r' not described in 'crush_choose_indep'
net/ceph/crush/mapper.c:655: warning: Function parameter or struct member 'choose_args' not described in 'crush_choose_indep'

These warnings are generated because the prologue comment for
crush_choose_indep() uses the kernel-doc prefix, but the actual
comment is a very brief description that is not in kernel-doc
format. Since this is a static function there is no need to fully
document the function, so replace the kernel-doc comment prefix with a
standard comment prefix to remove these warnings.
