Revision 607, 2.2 kB (checked in by ppalmers, 17 years ago)

- Fix file-based discovery. The previous code used a pointer to a

vendormodel entry. This pointer however pointed to a VendorModel?
object that was created on the stack of the discover function.
Hence the pointer becomes invalid when the discover function is
exited.

The changes incorporate using a VendorModelEntry? struct instead
of a pointer to it. So now the FFADODevice has it's own copy of
this struct, instead of a pointer to it.
