From 788d81d4e5d43ffc2dbcd4513dfec2808f5ff616 Mon Sep 17 00:00:00 2001 From: Magnus Lilja Date: Wed, 21 Dec 2016 22:13:58 +0100 Subject: dmaengine: ipu: Make sure the interrupt routine checks all interrupts. commit adee40b265d7568296e218f079f478197ffa15bf upstream. Commit 3d8cc00073d6 ("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).
