| 57 | * FUNCTION: acpi_ex_resolve_node_to_value |
| 58 | * |

| 60 | * a pointer to a NS node, and will receive a |
| 61 | * pointer to the resolved object. |
| 62 | * walk_state - Current state. Valid only if executing AML |

| 69 | * Note: for some of the data types, the pointer attached to the Node |
| 70 | * can be either a pointer to an actual internal object or a pointer into the |
