Hi Lee,

I am sorry I reply so late - I totally missed your comment/email.

I am not using devm intentionally, because there is cleanup path and
devm() would change the order of things are released.

The rule of thumb is: use devm or manual, don't mix, otherwise you ask
for trouble in weird cases.

Same for the other comment.

Best regards,
Krzysztof
