From 4d9efdfce73c8f0c9e39d118833e4776719a8d40 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 13 Jul 2015 20:39:54 +0000 Subject: dmaengine: ipu: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. This is also a preparation for the removal of the 'irq' argument from interrupt flow handlers.
