From 19808e0467a05ee4a3008f9d586ce32d5b34aba8 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 23 Sep 2016 17:19:42 +0200 Subject: [PATCH] iio:mma8452: Use new 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.
