From 80e84c16e72a0eac30085322b4664b7b6b0dde75 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Sun, 9 Feb 2014 09:59:14 +0800 Subject: [PATCH] crypto: ccp - Fix ccp_run_passthru_cmd dma variable assignments There are some suspicious looking lines of code in the new ccp driver, including one that assigns a variable to itself, and another that overwrites a previous assignment. This may have been a cut-and-paste error where 'src' was forgotten to be changed to 'dst'. I have no hardware to test this, so this is untested.
