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.
