Simon Guinot 863636828f dmaengine: fix interrupt clearing for mv_xor ... When using simultaneously the two DMA channels on a same engine, some transfers are never completed. For example, an endless lock can occur while writing heavily on a RAID5 array (with async-tx offload support enabled). Note that this issue can also be reproduced by using the DMA test client. On a same engine, the interrupt cause register is shared between two DMA channels. This patch make sure that the cause bit is only cleared for the requested channel.
