This is an i2c patch so the subject should be something like: i2c/pasemi: Remove hardcoded bus numbers on smbus And it should be sent to: wsa@the-dreams.de linux-i2c@vger.kernel.org linuxppc-dev@lists.ozlabs.org linux-kernel@vger.kernel.org cheers

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> --- v2 - remove unnecessary smbus->adapter.nr initialisation.
