ui: remove unreachable code in vnc_update_client
|
|

|

|

We can't cherry-pick those changes, however, because they depend
|
|
|
5d360b |
on the QIOChannel conversion. Thus, this downstream only change
|
|
|
5d360b |
is done to make other following changes apply with fewer conflicts
|
|
|
5d360b |
during backport.
