From bc0bb1fd5b0d72fba589b46be05c945171f9d6f3 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 4 Dec 2015 23:49:25 +0200 Subject: [PATCH] Revert "dmaengine: dw: platform: provide platform data for Intel" Since we have a work around to prevent a system hangup we don't need to provide a platform data explicitly anymore.
