[PULL 13/65] hw/acpi: Make storage of node id uint32_t to reduce fragility
Posted by Michael S. Tsirkin 2 weeks, 4 days ago
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

>From review of generic port introduction.

The value is handled as a uint32_t so store it in that type.
The value cannot in reality exceed MAX_NODES which is currently
128 but if the types are matched there is no need to rely on that
restriction.
