Subject: [PATCH] device: release removed devices from master on cleanup
|
|
|
fc9aca |
|
|
|
fc9aca |
On cleanup, unconditionally release a device from its master if the
|
|
|
fc9aca |
link is missing or it doesn't have a master, otherwise the master
|
|
|
fc9aca |
would later try to release the slave, hitting the following assertion:
|
|
|
fc9aca |
|
|
|
fc9aca |
"nm_platform_link_release: assertion 'slave > 0' failed"
