The AlpsPS/2 code previously relied on the assumption that `char` is a signed type, which was true on x86 platforms (the only place where this driver is used) before kernel 6.2. However, on 6.2 and later, this assumption is broken due to the introduction of -funsigned-char as a new global compiler flag.
Fix this by explicitly specifying the signedness of `char` when sign extending the values received from the device.
v2: Add explicit signedness to more places
v3: Use `s8` instead of `signed char`

Applied, thank you.
