That sounds like something outside the scope of the patch...
Why do you mean "used as s8"? Which function are you talking about?
You made me panic briefly because ATH9K_RXKEYIX_INVALID is a u8 so it
needs to be u8. I would have thought instinctively that u8 would be the
right type for an index like this.
