ide: fix 40-wire cable detection for TSST SH-S202* ATAPI devices (v2)
commit 8369d5fa63260cc54464b4687aa6a0f78402d98e upstream.
Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk:
commit 8588a2b732928b343233af9b1855705b8286bed4
("ide: add SH-S202J to ivb_list[]")
We also later added support for more such devices in:
commit e97564f362a93f8c248246c19828895950341252
("ide: More TSST drives with broken cable detection")
and in:
commit 3ced5c49bd2d1f2c7f769e3a54385883de63a652
("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]")
It turns out that such devices lack cable detection altogether
(which in turn results in incorrect detection of 40-wire cables
by our current cable detection strategy) so always handle them
by trusting host-side cable detection only.
v2:
Model detection fixup from Martin.
