Yes, that is what I was thinking of. Anyway, we can just test whether checkpatch --fix can d the change before proposing a semantic patch for it. julia -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I'm not quite sure what you're suggesting. You mean choosing pr_err vs pr_notice or something like finding an active struct and converting printks to _(, fmt, ...) from: { struct device *dev; ... printk(KERN_ERR "msg", ...) to: dev_err(dev, "msg", ...) checkpatch definitely can not do that.

[PATCH] Coccinelle: Script to drop parenthesis in the return statements
This script detects the use of a parenthesis around return value ot the return statements and removes them as they are unnecessary and against the CodingStyle. A new directory called checkpatch is added for semantic patches that just make patches for what checkpatch does. This will help developers having checkpatch problems, to run the semantic patches in this directory on their code and fix some of them automatically.
