Standard DMA, also called third-party DMA, uses a DMA controller. A DMA controller can generate memory addresses and initiate memory read or write cycles. It contains several hardware registers that can be written and read by the CPU. These include a memory address register, a byte count register, and one or more control registers. Depending on what features the DMA controller provid… WebPetersen, linux-scsi Cc: Ming Lei, Bart Van Assche, John Garry, Hannes Reinecke When scsi_add_host_with_dma() return failure, the caller will call scsi_host_put(shost) to release everything allocated for this host instance. So we can't free allocated stuff in scsi_add_host_with_dma(), otherwise double free will be caused.
