From: Sjur Brændeland <sjur.brandeland@xxxxxxxxxxxxxx> Remove buffers from the out-queue when a port is removed. Rproc_serial communicates with remote processors that may crash and leave buffers in the out-queue. The virtio serial ports may have buffers in the out-queue as well, e.g. for non-blocking ports and the host didn't consume them yet.
