From 8e7657ae0f56c14882e53ffdae8055c2b1624de1 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:12 +0100 Subject: ide: remove atapi_ireason_t (take 3) Remove atapi_ireason_t. While at it: * replace 'HWIF(drive)' by 'drive->hwif' (or just 'hwif' where possible) v2: * v1 had CD and IO bits reversed in many places. * Use CD and IO defines from . v3: * Fix incorrect "(ireason & IO) == test_bit()".
