Wait, shouldn't this check come ahead of all the other code since we're
basically overriding every other check with it?
Fixed.
Hm, not completely but well...
[PATCH] ide: add cable detection for early UDMA66 devices (take 3)
* Move ide_in_drive_list() from ide-dma.c to ide-iops.c.
* Add ivb_list[] table for listening early UDMA66 devices which don't conform
to ATA4 standard wrt cable detection (bit14 is zero, only bit13 is valid)
and use only device side cable detection for them since host side cable
detection may be unreliable.
* Add model "QUANTUM FIREBALLlct10 05" with firwmare "A03.0900" to the list
(from Craig's bugreport).
v2:
* Improve kernel message basing on suggestion from Sergei.
v3:
* Don't print kernel message when no device side cable detection is done,
plus some minor fixes. (Noticed by Sergei)
Thanks to Craig for testing this patch.
