Jeffrey Hugo a0e406be17 dmaengine: qcom: bam_dma: Fix resource leak ... commit 7667819385 upstream. bam_dma_terminate_all() will leak resources if any of the transactions are committed to the hardware (present in the desc fifo), and not complete. Since bam_dma_terminate_all() does not cause the hardware to be updated, the hardware will still operate on any previously committed transactions. This can cause memory corruption if the memory for the transaction has been reassigned, and will cause a sync issue between the BAM and its client(s). Fix this by properly updating the hardware in bam_dma_terminate_all().
