Does that config text really make sense?

It is reqired at least for one PXA based device. Ugh, why does it matter what it is named? Use udev, or a tool like it, to rename serial ports if you really need it, don't do this in the kernel please. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
