This can only happen if acpi_evaluate_integer(MEMORY_GET_BANDWIDTH) returned no-error and a bandwidth of zero (I assume). Is this a special case which the driver really wanted to handle?

Or is this all some big brainfart which should be removed? -- 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
