Ludovic Desroches d202f05158 dmaengine: at_hdmac: fix race condition in atc_advance_work() ... The BUG_ON() directive is triggered probably due to a latency modification following inclusion of commit c10d73671a ("softirq: reduce latencies"). This condition has not been met before 3.9-rc1 and doesn't trigger without this patch. We now make sure that DMA channel is idle before calling atc_complete_all() which makes the BUG_ON() "protection" useless.
