Subject: [PATCH] vchiq_arm: Service callbacks must not fail
|
|
|
|
|
|
|
|
|
|
Service callbacks are not allowed to return an error. The internal callback
|
|
|
|
|
that delivers events and messages to user tasks does not enqueue them if
|
|
|
|
|
the service is closing, but this is not an error and should not be
|
|
|
|
|
reported as such.
