tmspci driver uses dev->name before register_netdev() and so prints tr%d in initialization messages. Fix it by using dev_info. Found and tested on real hardware. Signed-off-by: Meelis Roos <mroos@linux.ee> Signed-off-by: David S. Miller <davem@davemloft.net>

* Modification History:
|
|
* 30-Dec-99 AF Split off from the tms380tr driver.
|
|
* 22-Jan-00 AF Updated to use indirect read/writes
|
|
* 23-Nov-00 JG New PCI API, cleanups
|

|
|
* TODO:
|
|
* 1. See if we can use MMIO instead of port accesses
