At the moment, attempting to probe a device with ST_LSM6DS3_ID
(e.g. using the st,lsm6ds3 compatible) fails with:
st_lsm6dsx_i2c 1-006b: unsupported whoami [69]
... even though 0x69 is the whoami listed for ST_LSM6DS3_ID.
This happens because st_lsm6dsx_check_whoami() also attempts
to match unspecified (zero-initialized) entries in the "id" array.
ST_LSM6DS3_ID = 0 will therefore match any entry in
st_lsm6dsx_sensor_settings (here: the first), because none of them
actually have all 12 entries listed in the "id" array.
Avoid this by additionally checking if "name" is set,
which is only set for valid entries in the "id" array.
Note: Although the problem was introduced earlier it did not surface until
