From fe06e5f9b7c61dc567edace3f4909672067f7d7e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 10 May 2010 21:41:39 +0200 Subject: libata-sff: separate out BMDMA EH Some of error handling logic in ata_sff_error_handler() and all of ata_sff_post_internal_cmd() are for BMDMA. Create ata_bmdma_error_handler() and ata_bmdma_post_internal_cmd() and move BMDMA part into those. While at it, change DMA protocol check to ata_is_dma(), fix post_internal_cmd to call ap->ops->bmdma_stop instead of directly calling ata_bmdma_stop() and open code hardreset selection so that ata_std_error_handler() doesn't have to know about sff hardreset. As these two functions are BMDMA specific, there's no reason to check for bmdma_addr before calling bmdma methods if the protocol of the failed command is DMA. sata_mv and pata_mpc52xx now don't need to set .post_internal_cmd to ATA_OP_NULL and pata_icside and sata_qstor don't need to set it to their bmdma_stop routines. ata_sff_post_internal_cmd() becomes noop and is removed. This fixes p3 described in clean-up-BMDMA-initialization patch.
