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 <linux/hdreg.h>. v3: * Fix incorrect "(ireason & IO) == test_bit()". (Noticed by Sergei) Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
