From: Dan Carpenter <dan.carpenter@oracle.com> commit a71266e454b5df10d019b06f5ebacd579f76be28 upstream. This is to silence a new Smatch warning: drivers/iio/imu/adis16400.c:492 adis16400_initial_setup() warn: sscanf doesn't return error codes If the condition "if (st->variant->flags & ADIS16400_HAS_SLOW_MODE) {" is false then we return 1 instead of returning 0 and probe will fail.
