As can be seen from the reviews:
- sleeps between DSI calls
- properly propagating the error at the end of the function
- making decision whether to create the context at the caller or the
callee side. E.g. in patch 8 it is better to allocate context in
hx8394_enable() and pass it to .init_sequence() instead of keeping
some of error handling.
