From a1bdeefd7bccabb265fa9c74811008a8582c1c7d Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 4 Jul 2012 17:09:00 +0100 Subject: [PATCH] staging:iio:dummy driver: Do not return error code in 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.
