| |
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.
