From ba84bd7146b9244de0ce04cdc668521a73f5336f Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 18 Oct 2012 17:34:11 +0300 Subject: [PATCH] dw_dmac: change dev_crit to dev_WARN in dwc_handle_error In case of handling a bad descriptor the dwc_handle_error() will dump a stack as well. It's a lot more verbose and more likely to get user's attention.
