Subject: [PATCH 06/20] intel_th: msu: Fix offset for wrapped block
Date: Mon, 15 Feb 2016 19:11:56 +0200 [thread overview]
Message-ID: <1455556330-12473-7-git-send-email-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <1455556330-12473-1-git-send-email-alexander.shishkin@linux.intel.com>
From: Laurent FERT <laurent.fert@intel.com>
Fix offset for the second pass on the wrapped block when iterating over
memory in multi-block mode, otherwise wrong part of the block will get
copied.
