If the function sdma_load_context() fails, the sdma_desc will be freed, but the allocated desc->bd is forgot to be freed. We already met the sdma_load_context() failure case and the log as below: [ 450.699064] imx-sdma 30bd0000.dma-controller: Timeout waiting for CH0 ready ... In this case, the desc->bd will not be freed without this change.
