From ba4b2e607e4e9eaa929935325dafd5c86d3b5262 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 23 Jul 2008 19:55:55 +0200 Subject: ide: remove dead Virtual DMA support Lets remove dead Virtual DMA support for now so it doesn't clutter core IDE code (it can be bring back when there is a need for it): * Remove IDE_HFLAG_VDMA host flag. * Remove ide_drive_t.vdma flag. * cs5520.c: remove stale FIXMEs, cs5520_dma_host_set() and cs5520_dma_ops (also there is no longer a need to set IDE_HFLAG_NO_ATAPI_DMA). There should be no functional changes caused by this patch.
