From d00e42dd26bbda6a39aead6a47c59221e03a08f8 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:06 +0100 Subject: [PATCH] ide-disk: fix taskfile registers loading order in __ide_do_rw_disk() Load IDE_SECTOR_REG after IDE_FEATURE_REG and IDE_NSECTOR_REG when using CHS. This patch is basically a preparation for the next one which converts __ide_do_rw_disk() to use struct ide_taskfile. It shouldn't affect anything (just a usual paranoia to separate changes which change the way in which hardware is accessed from code cleanups).
