i2c: pasemi: remove hardcoded bus numbers on smbus
The pasemi smbus controller uses PCI_FUNC(dev->devfn) to define which number bus to attach to, however this fails when something else is probed first, for example an ATI Radeon graphics card will claim 9 or 10 busses, including the ones the pasemi wants. Patch the driver to call i2c_add_adapter rather than i2c_add_numbered_adapter. Signed-off-by: Darren Stevens <darren@stevens-zone.net> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
