From 5c18d12ced225fa0ad5a03fb42bbb293815d1342 Mon Sep 17 00:00:00 2001 From: Darren Stevens <darren@stevens-zone.net> Date: Sun, 31 Dec 2017 20:53:55 +0000 Subject: [PATCH] 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.
