This one is a PCI driver, it doesn't do random I/O, so it should be
left as is. You did not experience a crash on PowerPC by loading this
driver, did you?

Okay. Thanks. And no, I didn't experience an Oops.

When sm_sis5595_init() gets called at module load time, it calls
pci_register_driver() to register sis5595_pci_probe(), which never
gets called.

Had sis5595_pci_probe() been called, it could have called
platform_driver_register() to register sis5595_probe(), which is
where we could potentially read/write the ISA address.

This is really a PCI I/O address and not an ISA address, by
construction. Any system with this PCI device would presumably properly
support said I/O operations.

Thanks for the clarification.


I'd added the "&&  !PPC" to this driver because it was in the list
of drivers you mentioned that I hadn't, when I first introduced this
issue. Sorry for misunderstanding. It's been removed from v2 of this
patch.

Oops, this is my fault then, sorry for the confusion. For my excuse,
this was before my pretty needed vacation ;)

My lack of understanding certainly played its part in all of this. :)
(Aren't vacations wonderful.)
