Colin Ian King e478abd4eb dmaengine: dw-axi-dmac: fix null dereference when pointer first is null ... [ Upstream commit 0788611c9a0925c607de536b2449de5ed98ef8df ] 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.
