Log:
Fix:
- Missing cpu_to_scr() added (endian-ness).
Improvement (fix|workaroung??):
- Blindly firing a PPR can lead to some messy situations due to
various causes or misfeatures, for example:
* The 53C1010-[33|66] supports offset 62 in DT mode, but only
offset 31 in ST mode. As a result, a PPR(DT, offset 62)
responded with PPR(ST, any offset > 31) must be rejected.
* A device that doesn't know about PPR should reject it, but
may also be confused by this message.
When a PPR encounters problems, the driver now patches the goal
transfer settings for legacy negotiations to be performed later
with the offending target. This give a chance for bad situations
to be fixed automagically.
