Shunyong Yang 0999f638a5 dmaengine: qcom_hidma: initialize tx flags in hidma_prep_dma_* ... [ Upstream commit 875aac8a46 ] In async_tx_test_ack(), it uses flags in struct dma_async_tx_descriptor to check the ACK status. As hidma reuses the descriptor in a free list when hidma_prep_dma_*(memcpy/memset) is called, the flag will keep ACKed if the descriptor has been used before. This will cause a BUG_ON in async_tx_quiesce(). kernel BUG at crypto/async_tx/async_tx.c:282! Internal error: Oops - BUG: 0 1 SMP ... task: ffff8017dd3ec000 task.stack: ffff8017dd3e8000 PC is at async_tx_quiesce+0x54/0x78 [async_tx] LR is at async_trigger_callback+0x98/0x110 [async_tx] This patch initializes flags in dma_async_tx_descriptor by the flags passed from the caller when hidma_prep_dma_*(memcpy/memset) is called.
