From 062f9f024dcdb927cfd35c9ee8a68f59cbb1136f Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 1 Feb 2008 23:09:32 +0100 Subject: ide: use ide_build_sglist() and ide_destroy_dmatable() in non-PCI host drivers * Make ide_build_sglist() and ide_destroy_dmatable() available also when CONFIG_BLK_DEV_IDEDMA_PCI=n. * Use ide_build_sglist() and ide_destroy_dmatable() in {ics,au1xxx-}ide.c and remove no longer needed {ics,au}ide_build_sglist(). There should be no functionality changes caused by this patch.
