But these are not "complex macros" that need an extra () added to them,
right?

Checkpatch is a hint, it's not a code parser and can not always know
what is happening. With your knowledge of C, does this look like
something that needs to be "fixed"?

Hi Greg,

Thanks for your reply.
Actually, I'm following the Eudyptula Challenge and I'm at task 10.
Task is to find and fix a coding style in linux-next/drivers/staging.
I've checked many files with checkpatch.pl but they are almost fine :)
I found this one and prepared a patch for it.
Thanks in advance for your comments and advice.

Thanks,
Fatih

First rule of that challenge is that you are not allowed to talk about
it in public :)

That being said, you didn't answer any of my questions above :(

Ohh no, missed the rule. Sorry for that, I feel rookie :)
You are right, they are not complex macros.
Besides that, type cast operator doesn't have the highest precedence.
So, I think we can use enclosing paranthesis.

I don't think they are needed, see how these are used please.
