Use scope based of_node_put() to simplify code. It reduces the chance
of forgetting of_node_put(), and also simplifies error handling path.
I not able to test the changes on all the hardwares, so driver owners,
please help review when you have time.

This patchset was inspired from Dan's comments on pinctrl-scmi-imx.c,
thanks.

Hi Peng,

thanks for doing this! I am very much in favor of using
scoped management of resources where it makes it easier to
do the right thing.

I agree with Krzysztof's comment that we should avoid scoping
in cases where there is a clear path grab/use/release so the
code is easy to read already as it is. Let's drop those.

I saw there was some patch that was even a fix, perhaps I
should pick that one separately for fixes, but probably it is
non-urgent.

I suppose we will just apply v2 after people had some time to
look at it!

Yours,
Linus Walleij

Yeah, will drop them in v2.

Not urgent, I will add fix tag in v2.

Thanks,
Peng.
