This is a note to let you know that I've just added the patch titled

    iio: adis16400: Fix an error code in adis16400_initial_setup()

Subject: iio: adis16400: Fix an error code in adis16400_initial_setup()

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.
