From 8a59fed39577d7313921a59dba8cc1711ae90da5 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 3 May 2013 15:32:04 +0100 Subject: dmaengine: ste_dma40: Remove 'always true' checking Before allocating memory for logical channels, the current driver checks to see if there are any. Well as the dma40_memcpy_channels[] array is always populated, the check is always true. Best to remove the check.
