From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 21:17:19 +0000 (+0100) Subject: ide: remove redundant DMA blacklist check from __ide_dma_on() X-Git-Tag: v2.6.25-rc1~1236^2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61a368c216897aa3bbee35b3f2e6db76ec73fad0;p=linux-2.6 ide: remove redundant DMA blacklist check from __ide_dma_on() ->ide_dma_on method is called only after successful ide_dma_check() call (ide_dma_check()->ide_tune_dma() checks DMA blacklist) or if drive->using_dma has been previously enabled for a given device (->ide_dma_on is the only place which sets drive->using_dma to '1'). There should be no functionality changes caused by this patch.
