Shouldn't it release buffers in this error case as well? It's generally a
bad design if a close/release/stop-like function can return an error, after
all, what should you do with that?

Same here, are you sure you can skip the rkisp1_destroy_dummy_buf call here?

This feels like more of a WARN_ON to me. It should never happen, right?

If start_streaming fails, then you need to return all buffers back to vb2 with
vb2_buffer_done(..., VB2_BUF_STATE_QUEUED). Just like in stop_streaming, but with
a different state. So please check all the error paths in this function.

You probably need a vb2_is_busy() call here. Normally you cannot change the selection
while streaming.
