From 4a98f896bf2c66a69517fc5e10dc67288cb8da93 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Mon, 10 Oct 2016 00:46:53 -0400 Subject: scsi: ncr5380: Use correct types for DMA routines Apply prototypes to get consistent function signatures for the DMA functions implemented in the board-specific drivers. To avoid using macros to alter actual parameters, some of those functions are reworked slightly. This is a step toward the goal of passing the board-specific routines to the core driver using an ops struct (as in a platform driver or library module). This also helps fix some inconsistent types: where the core driver uses ints (cmd->SCp.this_residual and hostdata->dma_len) for keeping track of transfers, certain board-specific routines used unsigned long. While we are fixing these function signatures, pass the hostdata pointer to DMA routines instead of a Scsi_Host pointer, for shorter and faster code.
