From: Borislav Petkov <petkovbb@xxxxxxxxx>
Date: Mon, 23 Feb 2009 07:58:23 +0100
Subject: [PATCH] ide: flags query macros
Add drive->atapi_flags and drive->dev_flags macro wrappers
v2:
- use static inlines for better typechecking
- use macro indirection for convenience
Signed-off-by: Borislav Petkov <petkovbb@xxxxxxxxx>
