PATCH 1/1 small cleanups for rtcan_peak_dng

Hi Wolfgang,

I came across the fact that xeno_can_peak_dng is autoloaded on 2.6 due to its PnP announcement via MODULE_DEVICE_TABLE. xeno_irqbench and xeno_16550A used to behave similar, but both just as well as this driver require manual parameters anyway. So let's remove the table and thus any autoloading tendency. I also cleaned up a few driver messages at this chance.

OK to apply?

Jan

Ja, sieht gut aus und bei dir funktioniert es ja auch.

Ein Kunde von uns evaluiert gerade CAN-Festival mit RT-Socket-CAN auf einem MPC5200-Board. Mal sehen, was dabei rauskommt.

Die Socket-CAN-Integration hat ja jetzt auch begonnen. Da bin ich mal gespannt. Sollte mal wieder die linux-netdev ML durchschauen.

Dann erstmal schöne Feiertage.

Viele Grüße,

Wolfgang.

Hello,

sorry, didn't realize the CC to the xenomai-core ML :-(. Here the English translation:

Yes, looks good and it's working for you, I assume.

FYI, a customer is currently evaluating CAN-Festival, a free CANopen implementation, with RT-Socket-CAN on a MPC5200. The rest is off-topic here.

FYI, the request for inclusion of Socket-CAN into the kernel has started on linux-netdev.

Have a nice weekend.
