pinctrl: Use scope based of_node_put() cleanups
|
expand
|
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

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.
