From 55f17e8da1f02ce0a36303a3f266c45045004cf5 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 11 Oct 2007 23:54:00 +0200 Subject: amd74xx/via82cxxx: use ide_tune_dma() * Use ide_tune_dma() in amd74xx/via82cxxx driver, this fixes following bugs: - DMA capability bit not being checked on the device - DMA blacklist not being checked - DMA mode being programmed even if drive->autodma == 0 (thus possibly destroying PIO timings) * Bump driver version.
