Right.
Please, read lore.kernel.org linux-media@ archives against this driver to
understand what to do with this patch.

Also, if you are in a group that is mentored, tell to the mentors to stop
looking into this driver by a newbie. This driver has much more urgent tasks
to do and it's not trivial, it also requires a real HW to be at hand to test.

The style is still wrong.

The above most likely already or should return a Linux error code in which case
the whole thing should be refactored,

	ret = ia_css_pipe_get_info(asd->stream_env[stream_index].pipes[pipe_index], &info);
	if (ret)
		dev_dbg(isp->dev, "ia_css_pipe_get_info FAILED");
		return ret;
	}
