I agree entirely.  The approach originally used in max1363 has gone in =
the latest
patch set posted the other day (indeed the set you reference below)

Yup.  That's what max1363 now does. In the same series, see
[PATCH 08/19] staging:iio:max1363 move to new abi.

(as the new abi didn't allow the 'named' scan mode approach!)

Other than some renaming, the lis3l20dq for example has done the scan_e=
lements
approach from the start (as have some of the others.)
