From ccf60d8571f0e606b5dacf213696b7a57fe2d890 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Sun, 27 Jan 2008 18:14:44 +0100 Subject: [PATCH] i2c-pasemi: use i2c_add_numbered_adapter() Use numbered adapter registration to always have the same hardware bus show up at the same number. PWRficient 1682M has three buses, they are all on the same PCI device but different functions. So do the simple thing and register them based on function number. Future products, if having a different number of busses, are expected to have similar behaviour w.r.t. device/function layout.
