Subject: [PATCH 06/11] Fix a crash when using fwupdtool
|
|
|
c5a379 |
|
|
|
c5a379 |
The docs for `fwupd_device_get_children()` make it very clear that only the
|
|
|
c5a379 |
parent should be assigned. Also add a warning to `fwupd_device_add_child()`
|
|
|
c5a379 |
explaining it is for internal daemon use only.
