Description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: at_hdmac: fix device leak on of_dma_xlate() Make sure to drop the reference taken when looking up the DMA platform device during of_dma_xlate() when releasing channel resources. Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing put_device() call in at_dma_xlate()") fixed the leak in a couple of error paths but the reference is still leaking on successful allocation.
