From 2ab3727634bf88583b40541ea32df6dadfb8cc6c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 19 Jun 2012 13:34:04 +0300 Subject: [PATCH] dw_dmac: print correct number of scanned descriptors In case the first descriptor we found is available, the counter still remains 0 value which is wrong. This patch fixes the counter behaviour.
