iio: imu: inv_mpu6050: make arrays hz and d static
Don't populate the arrays on the stack, instead make them static. Makes the object code smaller by 135 bytes: Before: text data bss dec hex filename 15135 4240 128 19503 4c2f inv_mpu_core.o After: text data bss dec hex filename 14840 4400 128 19368 4ba8 inv_mpu_core.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
