From 5aeddf907f149cae7e19b7c23ccea3823d00698c Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 13 Oct 2008 21:39:34 +0200 Subject: [PATCH] ide: unify conversion macros Introduce to_ide_drv() and ide_drv_g() macros and replace the respective definitions of similar ones in each driver. There should be no functionality change resulting from this patch.
