Revision 5228e39e3f709c82e6c4643402fc25de54391e32 authored by Stanimir Varbanov on 24 November 2015, 09:36:52 UTC, committed by Bjorn Helgaas on 24 November 2015, 20:06:41 UTC
"pp->io" is an I/O resource, e.g., "[io 0x0000-0xffff]"; "pp->io_base" is
the CPU physical address of a region where the host bridge converts CPU
memory accesses into PCI I/O transactions.
Corrupting pp->io_base by assigning pp->io->start to it breaks access to
the PCI I/O space, as reported by Kishon.
Remove the invalid assignment.
