Subject: ide: remove redundant ->ide_dma_on call from set_using_dma()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=23b1bd459c9e8a925381960f0b69ac85468c3af1;p=deliverable%2Flinux.git

ide: remove redundant ->ide_dma_on call from set_using_dma()

ide_set_dma() calls ->ide_dma_on method itself and returns zero
only if ->ide_dma_on call succeeded.

There should be no functionality changes caused by this patch.
