[PATCH] ide: remove atapi_ireason_t (take 2)
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>.
You're reading my mind. :-)

This won't work as IO is 0x02 and test_bit() returns 0 or 1.
