See also my answer there, the driver should still work as you expect it even with patch #6 applied. This patch is important to isolate the csrow handling that makes the code much better understandable and readable. I hope there are no concerns to this patch.

Have a separate function to count errors in csrow/channel. This better separates code and reduces the indentation level. No functional changes.
