Alex Elder f68c05c021 greybus: cancel operation on timeout ... If an operation times out, we need to cancel whatever message it has in-flight. Do that instead of completing the operation, in the timeout handler. When the in-flight request message is canceled its completion function will lead to the proper completion of the operation. Change gb_operation_cancel() so it takes the errno that it's supposed to assign as the result of the operation. Note that we want to preserve the original -ETIMEDOUT error, so don't overwrite the operation result value if it has already been set.
