Date: Sun, 20 Oct 2013 20:26:50 -0700 From: Benson Leung <bleung@...omium.org> To: wsa@...-dreams.de, mika.westerberg@...ux.intel.com, khali@...ux-fr.org, andriy.shevchenko@...ux.intel.com, jacmet@...site.dk, linux-i2c@...r.kernel.org, linux-kernel@...r.kernel.org Cc: dlaurie@...omium.org, bleung@...omium.org Subject: [PATCH 2/2] i2c-designware-pci: Index Haswell ULT bus names from 0 Rather than having the bus names be "i2c-designware-pci--1" because we have set the .bus_num to -1 to force dynamic allocation, lets have the busses named "i2c-designware-pci-0" and "i2c-designware-pci-1" to correspond to the correct names of these busses. The adapter number will still be dynamically assigned.
