From b82ed7d6805ef2a31503999edc80787083d4426f Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 4 Jul 2012 17:09:00 +0100 Subject: [PATCH] staging:iio:adis16260: Do not return error code in the interrupt handler The interrupt handler should only ever return one of the three irqreturn_t constants and not an error code. Also make sure to always call iio_trigger_notify_done before leaving the trigger handler.
