From 90bc49cd66f5cf28f3b1d5bf4621e5569c1b4901 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 3 Sep 2016 01:22:02 +0200 Subject: dmaengine: ipu: remove bogus NO_IRQ reference commit 86c7e6836479c4045a9a81ed5ea76c51d719f9c1 upstream. A workaround for a warning introduced a use of the NO_IRQ macro that should have been gone for a long time. It is clear from the code that the value cannot actually be used, but apparently there was a configuration at some point that caused a warning, so instead of just reverting that patch, this rearranges the code in a way that the warning cannot reappear.
