From 7183e68ef6cd8ef5c525256240de5f791ddf560d Mon Sep 17 00:00:00 2001 From: Magnus Lilja Date: Wed, 21 Dec 2016 22:13:58 +0100 Subject: [PATCH] dmaengine: ipu: Make sure the interrupt routine checks all interrupts. Commit 693fd86f9c84 ("dmaengine: ipu: Consolidate duplicated irq handlers") consolidated the two interrupts routines into one, but the remaining interrupt routine only checks the status of the error interrupts, not the normal interrupts. This patch fixes that problem (tested on i.MX31 PDK board).
