Sinan Kaya 793ae66c7d dmaengine: qcom_hidma: add error reporting for tx_status ... The HIDMA driver is capable of error detection. However, the error was not being passed back to the client when tx_status API is called. Changing the error handling behavior to follow this oder. 1. dmaengine asserts error interrupt 2. Driver receives and mark's the txn as error 3. Driver completes the txn and intimates the client. No further submissions. Drop the locks before calling callback, as subsequent processing by client maybe in callback thread. 4. Client invokes status and you can return error 5. On error, client calls terminate_all. You can reset channel, free all descriptors in the active, pending and completed lists 6. Client prepares new txn and so on. As part of this work, got rid of the reset in the interrupt handler when an error happens and the HW is put into disabled state. The only way to recover is for the client to terminate the channel.
