[PATCH 3/3] dmaengine: at_hdmac: add missing kfree() call in at_dma_xlate()

From: Yu Kuai
Date: Mon Aug 17 2020 - 07:57:58 EST


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.
