I know there are other DVB drivers that can have firmware compiled in instead of using FW_LOADER.

Looks like a mistake in the Kconfig file: - select FW_LOADER + select FW_LOADER if DVB_AV7110_FIRMWARE=n - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
