From: Thierry Reding <tred...@nvidia.com> i2c_bus_init() takes a bus number but relies on the currently selected bus to determine which adapter to initialize. Make the function use the bus passed in as parameter rather than the currently selected bus. While at it, keep a pointer to the specified bus to avoid having to look it up repeatedly.
