Subject: [PATCH 4/4] core, device-port: check availability when choosing the
|
|
|
43a070 |
default device
|
|
|
43a070 |
|
|
|
43a070 |
It doesn't make sense to use a sink or source whose active port is
|
|
|
43a070 |
unavailable, so let's take this into account when choosing the default
|
|
|
43a070 |
sink and source.
