staging: vt6656: Fix checkpatch unnecessary parentheses

Remove unnecessary parentheses - according to checkpatch.pl strict

Hi Teddy,

your patch creates a checkpatch warning:
WARNING: A patch subject line should describe the change not the tool that found it

The next thing that worries me is that the fix does not increase the readability of the code for me. I think overview is better with brackets.

I also think that you are doing two things at a time. You are changing the TODO file and the brackets.

I would change only the TODO file.

Thanks for your support.

Bye Philipp
