Subject: ide-pmac: add PIO autotune fallback to ->ide_dma_check
X-Git-Tag: v3.12-rc1~25836^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8b739d3361c16773a30fe5c0360336bbc19f435;p=kernel%2Fkernel-generic.git

ide-pmac: add PIO autotune fallback to ->ide_dma_check

Since ide-pmac allows separate PIO and DMA timings, and ide-pmac always sets
->autotune this change shouldn't have any other effect than bringing ide-pmac
driver in-line with other host drivers wrt ->ide_dma_check implementation.
