CVE-2022-49746

Description

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: imx-sdma: Fix a possible memory leak in sdma_transfer_init

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.
