According to the kernel coding style, reducing superfluous parentheses makes the code more readable and straightforward. There are no functional changes; it’s purely a cleanup to align the code with kernel style guidelines.

Please wrap your changelog at 72 columns like your editor asked you to.

No, please see the zillions of times I have rejected changes like this
in the past on the mailing list.  checkpatch.pl is wrong here.

We write code for people first, compilers second.  With your change, now
you need to look up the order of operations (quick, which is comes first
in order, '&&' or '!' or '>')?

With the () there, you know what the intent is, and what the order is,
without having to always know what comes before what.
