New Revision: 292579
URL: https://svnweb.freebsd.org/changeset/base/292579
Log:
Fix the detection of IO/memory space changing across busses when the bus
is not pci (and thus where, ironically, the whole situation is meaningless).
This was not an error in the original code, it was introduced during my
refactoring to commonize the routine. A small change a few lines above
drove the need to make this change, and the error didn't show up on the
platforms I initially tested with.
