3.8.13.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
commit c481420248c6730246d2a1b1773d5d7007ae0835 upstream.
Fix to return -ENOMEM in the allocation error case instead of 0 (if pmu_bus_running == 1), as done elsewhere in this function.
