Colin Ian King 0788611c9a dmaengine: dw-axi-dmac: fix null dereference when pointer first is null ... In the unlikely event that axi_desc_get returns a null desc in the very first iteration of the while-loop the error exit path ends up calling axi_desc_put on a null pointer 'first' and this causes a null pointer dereference. Fix this by adding a null check on pointer 'first' before calling axi_desc_put.
