[PATCH v1 01/12] dmaengine: dw: move dw_dmac.h to where it belongs to
From: Andy Shevchenko
Date: Tue Aug 19 2014 - 13:32:14 EST
There is a common storage for platform data related structures and definitions
inside kernel source tree. The patch moves file from include/linux to
include/linux/platform_data and renames it acoordingly. The users are also
updated.
