Coverity reports a potential integer overflow in the accel_range computation due to the use of a left shift on an int type.
CID 520269: Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
Even though the register value is constrained to 0–3 by the BMA456 spec, and no real overflow occurs, an explicit cast to int64_t prevents false positives and aligns with safe coding practices.
