From: Bartlomiej Zolnierkiewicz Date: Tue, 16 Oct 2007 20:29:54 +0000 (+0200) Subject: cs5530/sc1200: add PIO autotune fallback to ->ide_dma_check X-Git-Tag: v2.6.24-rc1~822^2~17 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3f019eea9ccff0e81d3226759a619ceec26e2e00;p=linux-2.6-omap-h63xx.git cs5530/sc1200: add PIO autotune fallback to ->ide_dma_check * Add PIO autotune fallback to ->ide_dma_check. Since cs5530/sc1200 allow separate PIO and DMA timings, and cs5530/sc1200 always set ->autotune this change shouldn't have any other effect than bringing these drivers in-line with other host drivers wrt ->ide_dma_check implementations. * Fix ->ide_dma_check to return "-1" if DMA cannot be set. * Bump driver version.
