From bea15d5139b9eef3ca368b95c4dbd6621bff9a5c Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 23 Sep 2016 17:19:43 +0200 Subject: [PATCH] iio:max1027: Use iio_trigger_validate_own_device() helper Use the new iio_trigger_validate_own_device() to verify that the trigger can only be attached to the matching IIO device rather than using a custom variant. While the implementation of iio_trigger_validate_own_device() and the custom variant and are not identical their behaviour is.
