What the driver is doing is, unfortunately, the best practice for an AC'97 connected device like this - we've got an uncomfortable mix of an enumerable bus and platform data combined with a subsystem which has never had enough love to work in a nice way with the kernel. The idea is that any boards which have the device will call the _set_data() function in their board-specific code. Sadly we're a little short on volunteers to clean up the AC'97 subsystem so this situation shows little sign of improving. -- 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/
