Subject: ide: remove redundant DMA blacklist check from __ide_dma_on()
X-Git-Tag: v2.6.25-rc1~1236^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61a368c216897aa3bbee35b3f2e6db76ec73fad0;p=pandora-kernel.git

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.
