sparc: sbus: treat CPU index as integer
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. Cc: David S. Miller <davem@davemloft.net> Signed-off-by: Jason A.
