[media] coda: issue seq_end_work during stop_streaming (f4706d6e) · Commits · 戴 / test

This patch queues seq_end_work and flushes the queue during stop_streaming and clears the ctx->initialized flag. This allows to start streaming again after stopping streaming without releasing the context. Signed-off-by:
