The brightness and contrast paths use oldvalue after read_reg_fp() without checking whether the read succeeded. A failed read leaves oldvalue uninitialized and can write arbitrary reserved register bits. Return read and write errors from every control path so failed hardware access cannot be reported as a successful control update.
