Only minor changes this time. I dropped the implementation of the selection api, removed all references mentioning the decoder, and fixed a few issues reported by sparse and smatch.

The driver always queues the event before returning the last buffer and the "MMAP (epoll)" does not fail. Thus, I decided to send the series anyway.
