Messages in this thread Patch in this message | | | From | Tomeu Vizoso <> | Subject | [PATCH v1 06/10] ACPI / scan: Add acpi_dev_get_next_child() | Date | Tue, 30 Jun 2015 16:55:04 +0200 |
| |
So fwnode_get_next_child_node() can be implemented for ACPI firmware nodes.
This re-implements acpi_get_next_child() in terms of acpi_dev_get_next_child().
