From 8987d21ba6a426b0685257866ce366055930b57f Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 20 Jul 2007 01:11:56 +0200 Subject: ide: ide_start_power_step() fix WRT disabling DMA * Do the same thing as probe_hwif() and always disable DMA so chipset DMA enabled bit gets cleared (if the drive doesn't support DMA ide_set_dma() won't try to tune it anyway). * Add TODO comment about respecting ->using_dma setting.
