From fec86c6b8369b5dd8e3a1ad3752578a737163b25 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nuno=20S=C3=A1?= Date: Mon, 13 Apr 2020 10:24:40 +0200 Subject: iio: imu: adis: Add Managed device functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for a managed device version of adis_setup_buffer_and_trigger. It works exactly as the original one but it calls all the devm_iio_* functions to setup an iio buffer and trigger. Hence we do not need to care about cleaning those and we do not need to support a remove() callback for every driver using the adis library.
