If you can change it to dev->name instead of "tile_net", feel free to add my: Acked-by: Chris Metcalf <cmetcalf@tilera.com>

This module is loaded once and for all when the first network device is brought up, so this request_irq is for all the tile network interfaces. Suppose you "up" gbe0, "up" gbe1 and "down" gbe0, the device name would still be gbe0, even though it's down. That's why I opted for a generic name instead. If you still want to go with dev->name I have no problem with that. > Acked-by: Chris Metcalf <cmetcalf@tilera.com> > > -- > Chris Metcalf, Tilera Corp. > http://www.tilera.com > -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It does probably make more sense to use "tile_net". So apply my Acked-by to your patch as-is. Thanks!

This patch simply makes the tilegx net driver call request_irq with a non-null name. It makes the output in /proc/interrupts more obvious, but also helps tools that don't expect to find null there.
