ignores the return value of sdma_txinit_ahg().\n\nIf sdma_txinit_ahg() fails, it returns before initializing tx->txreq.\nHowever, set_txreq_header_ahg() ignores the error and returns the AHG\nchange count, causing the caller to continue processing the request as\nthough initialization had succeeded.\n\nPropagate sdma_txinit_ahg() failures to the caller and abort request\nprocessing when initialization fails.\n\nFound by Linux Verification Center (linuxtesting.org) with
