| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dmaengine does not provide a way to pass back the result from a DMA transaction through the callback function. We are adding dmaengine helper function in order to prep for a mechanism that allow result status and other information through the callback. The initial conversion will make the existing driver use these new helper functions but retain the original behavior of the code. However, the helper functions paves a way towards adding the result parameter through callback.
