From 3f019eea9ccff0e81d3226759a619ceec26e2e00 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 16 Oct 2007 22:29:54 +0200 Subject: 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.
