From 0d346ba0730d84f04022f9f984d3f606f69cef37 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:38 +0200 Subject: ide: sanitize ide*_pm_* enums * Move ide*_pm_* enums from ide-io.c to . * idedisk_pm_* -> ide_pm_* * ide_pm_state_* -> ide_pm_* * No need to set ide_pm_* enums to the fixed values. * Uppercase ide_pm_* enums. * Fix/update comments.
