If there is default firmware then even if it's not particularly useful the kernel should probably not *require* that additional firmware is provided during driver startup - the system may wish to wait until later in the boot to provide it, for example because it needs to mount media to get to the firmware or because it needs to do additional work to decide what firmware is required for the current system setup. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
