Yu Kuai 395173c0ba dmaengine: at_hdmac: check return value of of_find_device_by_node() in at_dma_xlate()
[ Upstream commit 0cef8e2c5a ]

The reurn value of of_find_device_by_node() is not checked, thus null
pointer dereference will be triggered if of_find_device_by_node()
failed.

Fixes: bbe89c8e3d ("at_hdmac: move to generic DMA binding")
