From 75d7d963e3dcf8a1410000ab246921709e276cd9 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 13 Oct 2007 17:47:50 +0200 Subject: icside: use ide_tune_dma() * Add "good DMA drives" hack for icside to ide-dma.c::ide_find_dma_mode() (in the long-term it should be either removed or generalized for all hosts). * Use ide_tune_dma() in icside.c::icside_dma_check(). This results in the following changes in behavior: - pre-EIDE SWDMA modes are now also respected - drive->autodma is checked instead of hwif->autodma (doesn't really matter as icside sets both to "1") * Make ide-dma.c::__ide_dma_good_drive() static and drop "__" prefix.
