From 8f913bffb4d35718914c1ecc8c1f52c216925752 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Wed, 14 Sep 2016 15:39:56 +0530 Subject: [PATCH] dmaengine: ep93xx: don't use variables defined in global scope The driver uses same variable name in local and global context in a function, rename the local one for better readability.
