Nuno Sá Sept. 15, 2020, 12:02 p.m. UTC
Use the adis managed device functions to setup the buffer and the trigger.
The ultimate goal will be to completely drop the non devm version from
the lib.

Since we are here, drop the `.remove` callback by further using devm
functions.

Signed-off-by: Nuno Sá <nuno.sa@analog.com>

Changes in v2:
* Further use devm functions to keep cleanup order and to drop `.remove`.
