dm flakey: return -EINVAL on interval bounds error in flakey_ctr()
Fix to return error code -EINVAL instead of 0, as is done elsewhere in this function. Fixes: e80d1c805a3b ("dm: do not override error code returned from dm_get_device()") Cc: stable@vger.kernel.org # 4.3+ Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
