dmaengine: at_hdmac: add missing kfree() call in at_dma_xlate()
commit5.4-rM2-2.2.x-imx-squashede097eb7473
upstream. If memory allocation for 'atslave' succeed, at_dma_xlate() doesn't have a corresponding kfree() in exception handling. Thus add kfree() for this function implementation. Fixes:bbe89c8e3d
