zero, the change has no effect

e5687979eb iio🔍mag3110 replaces IIO_ST macro with explicit entries to struct scan_type 
The IIO_ST macro no longer covers all the elements of struct scan_type
and has this has lead to some bugs being introduced.

The drivers are easier to follow with this structure being directly
filled so that is now preferred.
