Constants that are to be used in bitwise operations should be unsigned,
or a user could easily trigger Undefined Behavior.
Also, the types where these constants are to be assigned are unsigned,
so this makes it more consistent.

Here it is. :)

I compiled the kernel, and it seems ok; didn't test more than that.
Have a lovely day!
