Using a `char` to fit a CPU index is too small, and assigning -1 to it
isn't correct either, since `char` is sometimes signed and sometimes
not. In this case, it's been fine since this driver only works on sparc,
but that will soon be changing when chars become unsigned everywhere. So
instead, use a normal `int` type, which matches the `int cpu` function
argument that this is being compared against.

DaveM - this is part of the -funsigned-char work I've been accumulating
in my unsigned-char branch. If you want to take this as a fix for 6.1,
go ahead. Otherwise, Linus asked me to keep the 6.2 unsigned-char
patches together in my branch, so I'll take this, pending your Ack.
