From 97100fc816badbbc162644cfde7ad39ae9211fb4 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:36 +0200 Subject: ide: add device flags Add 'unsigned long dev_flags' to ide_drive_t and convert bitfields to IDE_DFLAG_* flags. While at it: - IDE_DFLAG_ADDRESSING -> IDE_DFLAG_LBA48 - fixup some comments - remove needless g->flags zeroing from ide*_probe() There should be no functional changes caused by this patch.
