From 51c9daec79b4fa8140cd5490abec4f1f3685ecd8 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Fri, 28 Oct 2022 16:22:56 +0200 Subject: 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 Signed-off-by: Jason A.
